While dragging a tab, the strip scrolls within edge zones proportional to penetration, stops outside strip and clamps movement to available scroll range.

Why this case matters

Offline tab/panel workspace behavior; no browser or desktop framework is emulated.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
