Menu item activation: Reactivating a selected menu radio clears its selection · case 05

Reactivating a selected menu radio clears its selection.

Member previewVariant 5 · 3 implementations · 13 checks per implementation

Case contract

Disabled items and nonactivation keys do nothing; click, Enter and Space activate; submenu transfers focus; checks toggle; radios select; leaf commands close.

Why this case matters

A deterministic model of menu item activation; this isolates one interface invariant without requiring a browser.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
radio stays	`[true, false, "change"]`	`[true, true, "change"]`	Failed
