 * back to the browser makes the gesture work. Dockview's overlay scrollbar
 * stays the visible affordance and follows along (it syncs from the element's

/* Tabs shrink before the strip clips them.
 *
 * Dockview pins `.dv-tab` at `flex-shrink: 0`, so a group narrower than its tab
 * row kept every tab at full width and the strip clipped the row from the
 * right. The close button sits at a tab's right edge, so it was the first thing
 * to disappear and a tab could become impossible to close without widening the
 * group again. Shrinking down to a floor truncates the label instead and keeps
 * the close button in view; past the floor Dockview's own overflow dropdown
 * takes over.
 *
 * The floor is 4rem because that leaves a few characters of label beside the
 * close button, and because it sits just under the natural width of the
 * shortest panel titles ("Plan", "Files") so the common case is not widened. */
