This PR addresses an issue where queries cannot be performed in the mobile menu, particularly on Android devices. The root cause was that the `event.key` of keypress returns 'Unidentified' on Android, which prevented proper query handling.
Changes made:
- Replaced the keydown event observer with a beforeinput event listener
- Removed unnecessary keyboard event handling code that was causing issues
