An animation with more rows than the panel is tall cut the bottom rows off. There was no way to reach them, their fields or their keys. - The view has a new `scrollY`. Rows scroll up under the ruler, which stays where it is together with the tab head. - The wheel over the header column scrolls the rows. Over the cells it still zooms, and `Shift`+wheel still scrolls across. - A scrollbar at the right edge shows up only when the rows do not fit. Its thumb can be dragged, a click beside it jumps there. - The middle button pans both ways. `Shift`+drag stays across only. - A row picked or added out of view is scrolled just far enough to be seen whole. Value fields out of view are not drawn. - The tab keeps its scroll like its zoom when switching. Found on the way: `zoomCells` built a new view from `panX` and `cellWidth` only, so every zoom would have dropped the scroll. The type check caught it, and a unit test now holds it. Tests: - tsc, eslint, Prettier clean - Unit timeline-view: 20 green, 6 new. Bending `rowAt` to ignore the scroll or `revealRow` to do nothing turns exactly those tests red. - e2e 25 on melektaus-atx: ALL PASSED, 37 checks (25j, 25j-ii new). 32 rows, the wheel brings the last field into view and typing keys 77 there. Dragging the thumb up goes back to 0. - Gate on melektaus-atx: green, 305 files, 4730 tests. - Not checked in the browser: the middle button, revealing a picked row, the wheel right over a value field.
