251af2c added a `?.` on cursorRef in onGridClick but inadvertently
deleted the closing braces, the trailing reset block, and the
onKeyDown/onKeyUp/onCancel handlers — leaving onGridClick syntactically
unterminated and three undefined references at the emitter.on/off sites.
Restores the deleted block verbatim, keeping the optional-chaining null
guard on cursorRef.
