Panel background tasks: background index retention · case 03

The tab workspace reports an incorrect background index retention.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Tab panel jobs are classified into visible rendering, background-safe work and paused work. Hidden panes pause render-only jobs but retain explicit background-safe tasks.

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 0	`[[["a", "render"]], [["b", "render"]], [["a", "index"]], [["c", "render"]], ["b"], [["a", "render"], ["a", "index"], ["b", "index"], ["extra0", "index"], ["extra1", "index"]]]`	`[[["a", "render"]], [["b", "render"]], [["a", "index"], ["b", "index"], ["extra0", "index"], ["extra1", "index"]], [["c", "render"]], ["b"], [["a", "render"], ["a", "index"], ["b", "index"], ["extra0", "index"], ["extra1", "index"]]]`	Failed
