fix(editor): zoom/pan the whole timeline pane on scroll - #467
Conversation
… lanes The wheel listener lived on .tlTracks alone, so Ctrl/Shift+scrolling over the ruler, the hint labels, or the nav bar did nothing — only scrolling over the lanes zoomed or panned.

219-229: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winCover Shift+wheel panning over a non-track target.
The listener change handles both Ctrl+wheel zoom and Shift+wheel pan. This regression test covers only Ctrl+wheel on the ruler. Add a Shift+wheel case on the ruler or navigation bar and assert that the viewport window changes. This prevents a regression in the panel-wide pan path from passing the test suite.
As per coding guidelines, add a test for every new behavior in the same package as the code under test.

CodeRabbit flagged that the panel-wide wheel fix only had regression coverage for Ctrl+wheel zoom from the ruler, not Shift+wheel pan.
|
Good catch — added a Shift+wheel pan regression test on the ruler in 5b69a2f, symmetric to the existing Ctrl+wheel zoom one. |
