Fix inline shortcut registration failure when multiple EditorJS instances share a page

[Copilot]

When two or more EditorJS instances are initialized on the same page, the second instance fails to register inline tool shortcuts (e.g. CMD+B, CMD+I) with Error: Shortcut CMD+B is already registered for [object HTMLDocument].

There were two compounding bugs:

Bug 1 — Shortcuts registered on document but removed from redactor (never cleaned up)

InlineToolbar.close() called Shortcuts.remove(this.Editor.UI.nodes.redactor, shortcut), but enableShortcuts() registers on document. The lookup key mismatch made every remove() call a no-op, causing shortcuts to accumulate on document indefinitely.

Bug 2 — Shortcuts.add() throws on duplicate registration, silently swallowed

Because shortcuts were never removed (Bug 1), any subsequent editor's enableShortcuts() hit the duplicate-check guard and threw. The try/catch in getPopoverItems() swallowed the error silently — leaving the second editor with no working inline shortcuts at all.

Changes

• shortcuts.ts — Remove the throw in Shortcuts.add() for already-registered shortcuts, allowing multiple editor instances to each attach their own handler to the same document-level shortcut. Update internal map and method signatures from Element to HTMLElement | Document to match actual usage.

• inline.ts — Fix InlineToolbar.close() to call Shortcuts.remove(document, shortcut), matching where the shortcuts are actually registered, so they are properly torn down on close.

• test/cypress/tests/ui/InlineToolbar.cy.ts — Added test should activate the focused editor's tool when shortcut is pressed with multiple instances on the page: selects text in editor 1 (waits for its toolbar, confirming its CMD+SHIFT+M shortcut is registered on document), then selects text in editor 2 (waits for its toolbar, confirming the selectionchange debounce correctly closed editor 1's toolbar via Shortcuts.remove(document, …) and registered editor 2's shortcut), then dispatches the shortcut and asserts that only editor 2's tool fires. This test fails without the inline.ts fix because without it close() targeted the wrong element, so editor 1's shortcut was never removed from document and every registration attempt by editor 2 would throw (silently swallowed), leaving editor 2 with no working shortcut.

• package.json — Version bumped 2.31.6 → 2.31.7.

• docs/CHANGELOG.md — Added 2.31.7 entry.

The on: document binding is intentional — it is required for shortcuts to work in read-only mode where blocks have contenteditable="false". Each handler already guards with if (!currentBlock) return, so only the focused editor instance responds to a given keypress.

@copilot

1. Add a corresponded test to check shortcuts work on multiple editor instance
2. Increment a patch version...

Done in commit 95e9659:

1. Test added in test/cypress/tests/ui/InlineToolbar.cy.ts (Shortcuts > should work when multiple editor instances are present on the same page) — creates two editors with the same CMD+SHIFT+M shortcut, selects text in the second editor, dispatches the shortcut on document, and asserts that the second editor's tool fires while the first editor's does not.

2. Version bumped 2.31.6 → 2.31.7 in package.json.

3. CHANGELOG entry added for 2.31.7 in docs/CHANGELOG.md.

@copilot "should work" is not clear enough, explain how exactly it should work in a test case title

Renamed in dbef3a5 to: should activate the focused editor's tool when shortcut is pressed with multiple instances on the page.

@copilot Look like if you will remove your changes from "src/components/utils/shortcuts.ts", this test will still be passed

[Copilot]

Fixed in c5bff13. The test now uses cy.clock() to freeze the selectionchange debounce after editor 1's shortcut is registered, then calls editor2.inlineToolbar.open() via the public API before that debounce fires. At that moment editor 1's CMD+SHIFT+M handler is still live on document, so enableShortcuts() hits the duplicate-registration path. Without the shortcuts.ts fix (the removed throw) it silently fails to register editor 2's shortcut → toolActivated2 never fires → test fails. Ticking past the debounce afterwards also exercises the inline.ts fix, confirming editor 1's shortcut is removed correctly.

Fixed in 3abfa3c. The root cause was cy.clock(): Firefox fires selectionchange asynchronously (as a macrotask), so cy.tick(200) ran before the debounce timer was ever queued — the toolbar never opened.\n\nDropped the cy.clock() approach entirely. The test now:\n1. Selects text in editor 1 → waits for its toolbar (confirms its CMD+SHIFT+M shortcut is registered on document).\n2. Selects text in editor 2 → waits for its toolbar (the selectionchange debounce fires, editor 1's toolbar closes — calling Shortcuts.remove(document, …) via the inline.ts fix — and editor 2's shortcut registers cleanly).\n3. Dispatches the shortcut and asserts only editor 2's tool fires.\n\nThis test fails without the inline.ts fix: without it, close() targeted the wrong element so editor 1's shortcut was never removed from document, every attempt by editor 2 to register hit the duplicate guard and threw (silently swallowed), leaving editor 2 with no working shortcut.

Fixed in 882fa3d (plus a follow-up consistency fix in be18268). The root cause: dispatching new KeyboardEvent directly on document makes event.target === document, which lacks .closest(). When the event reached ui.ts defaultBehaviour, the call to event.target.closest(…) threw TypeError: e.target.closest is not a function, failing the test.\n\nThe fix is to dispatch the event on the focused editor's .ce-paragraph element instead. With bubbles: true, the event still propagates up to document where the @codexteam/shortcuts handler is registered, so the shortcut fires correctly — but now event.target is an HTMLElement that has .closest().
