- Added comprehensive comments to `js/webtorrent.js` explaining the playback strategy, service worker integration, and browser-specific quirks (Brave/Firefox).
- Patched `tests/ui/helpers/jsdom-test-helpers.mjs` to expose `HTMLStyleElement` and other globals to JSDOM, fixing `ReferenceError` in UI tests.
- Fixed `tests/ui/similar-content-card.test.mjs` to align with the current component implementation (handling detached elements) and resolving environment issues.
- Updated `tests/video-modal-accessibility.test.mjs` to safely mock `navigator` and `HTMLCanvasElement.getContext`, resolving `TypeError` and "Not implemented" errors during testing.
This addresses an issue where comments would not display on the first load of the video modal if the DOM elements were not fully bound. The `open()` method now checks if the `commentsList` is missing or disconnected and re-initializes the `CommentsController` if necessary.
Also updated `tests/video-modal-accessibility.test.mjs` to fix a JSDOM environment issue with `navigator` mocking.
