Rating preview and committed value: Activation retains an obsolete hover preview · case 04

Activation retains an obsolete hover preview.

Member previewVariant 4 · 3 implementations · 12 checks per implementation

Case contract

Hover changes preview only; leaving or Escape discards preview; activation commits and clears preview; repeated activation clears only when allowed; readonly ignores interaction and has no preview.

Why this case matters

A deterministic model of rating preview and committed value; this isolates one interface invariant without requiring a browser.

One recorded failure
