Typing does not reveal available suggestions.

Member previewVariant 2 · 3 implementations · 10 checks per implementation

Case contract

Escape discards query but preserves committed value; Enter commits only an existing active option in an open popup; Tab closes without commit; Clear resets both; typing opens suggestions.

Why this case matters

A deterministic model of combobox keyboard commit; this isolates one interface invariant without requiring a browser.

One recorded failure

Sample boundary fixture
