`_https://example.com/a_` not parsed correctly

[nschloe]

Describe the bug

MWE:

from markdown_it import MarkdownIt
from markdown_it.tree import SyntaxTreeNode

md = MarkdownIt("gfm-like")

# okay:
tokens = md.parse("_https://example.com_")
print(SyntaxTreeNode(tokens).pretty())

# bug:
tokens = md.parse("_https://example.com/a_")
print(SyntaxTreeNode(tokens).pretty())

Output:

<root>
  <paragraph>
    <inline>
      <em>
        <link href='https://example.com'>
          <text>
<root>
  <paragraph>
    <inline>
      <text>
      <link href='https://example.com/a_'>
        <text>

Note how the underscore is incorrectly included in the last link.

linkify-it-py works the same as linkify-it as specified. This is not a bug.

The solution is to enclose it in <>.
For example, _<https://example.com>_, _<https://example.com/a>_.
