Summary

Closes #904.

An open Autocomplete can still change the input and fire onSelect after disable(). Check the plugin’s disabled state in the delegated suggestion click handler, as the keyboard handlers already do.

Reproduction

Type Al into an input with Alpha and Alpine as local suggestions. Call disable() while the suggestions are open, then click Alpine.

Test plan

• npm test (43 passed). The new test fails on the original source and passes with the change. It also verifies that selection works after enable().
• npm run lint, npm run format:check, npm run typecheck, and npm run build.
• A normal Chrome click after disable() preserves Al and leaves the callback count at zero.
