keydown triggers when tapping result

Nobody has claimed this yet.

i don't want to reopen the results when a result is tapped.

i'm not sure why this is happening on my mobile, but i disabled the keydown listener since i'm not using it anyway.

```
export default class Geocoder extends MapboxGeocoder {
onAdd(...args) {
const addEventListener = EventTarget.prototype.addEventListener;
EventTarget.prototype.addEventListener = function (type, ...args) {
if (type !== 'keydown') {
// the debouncing causes the options to open when a result is tapped
addEventListener.call(this, type, ...args);
}
};
const el = super.onAdd(...args);
EventTarget.prototype.addEventListener = addEventListener;

return el;
}
}
```

Start at the Geocoder.onAdd entry point and inspect how the keydown listener and result-tap handling interact, including the debouncing mentioned in the report. Reproduce the mobile behavior described in the issue, then verify that tapping a result does not reopen the results.
