The tab workspace reports an incorrect matching transfer receipt.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

A tab tearoff retains the source until the destination acknowledges the exact transfer. Failure restores source placement; duplicate acknowledgements do not remove another tab.

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.

Boundary fixture	Actual	Expected	Outcome
workspace regression 1	`[true, true, ["a", "b", "c"], false, false, false]`	`[false, true, ["a", "b", "c"], false, false, false]`	Failed
