Menu item activation: Disabled menu commands still invoke actions · case 03

Disabled menu commands still invoke actions.

Member previewVariant 3 · 3 implementations · 11 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
