This commit adds support for using the Lightpanda headless browser instead of Playwright for browser-dependent tests. Changes: - Add capybara-lightpanda gem to the test group - Configure CI workflow to download and cache Lightpanda binary - Add spec/support/lightpanda.rb for Capybara driver configuration - Remove experimental gems (cuprite, selenium-webdriver, lightpanda-ruby) Usage: LIGHTPANDA=true bundle exec rspec spec/features/ The LIGHTPANDA_PATH environment variable can be used to specify the path to the lightpanda binary (defaults to auto-download). Benefits: - Lighter weight (~65MB binary vs ~150MB+ Chromium) - No complex browser installation in CI - Self-contained CDP client - Comparable test performance to Playwright
- Use the 'from' parameter as element ID instead of hardcoded value - Add longer wait times when LIGHTPANDA=true for JavaScript execution - Fixes test failures in managing_meeting_invitations_spec

This was a fun experiment, good learnings. One day Lightpanda will be good enough to run our tests |

Summary
This PR tests replacing Playwright with Lightpanda for browser-dependent tests in CI.
Changes
capybara-lightpandagem for Capybara integrationUsage
Benefits
Limitations Found⚠️
TomSelect/JavaScript Compatibility: Lightpanda's JavaScript engine doesn't fully support complex DOM manipulation libraries like TomSelect. Tests using TomSelect dropdowns fail because the library doesn't initialize properly.
Root Cause:
tsWrapperClass="ts-wrapper tom-select single..."✅tsWrapperClass="N/A"❌This is a fundamental limitation of Lightpanda's JavaScript engine (QuickJS) compared to full Chrome V8.
Local Testing Results
Based on 6 runs of 12 browser-dependent tests:
CI Results
Conclusion
Not ready for production - Lightpanda shows promise with ~20% faster execution on compatible tests, but the JavaScript compatibility issues prevent full test suite passage.
Recommendation:
Status: DRAFT - Experimental, do not merge
