# Objective

Fixes #63774

## Solution

On Wayland, the IME remained enabled when the focused control did not
register a text input handler. This allowed IME to intercept ABC...Z
character shortcuts in non-text UI, including the Project Panel outside
filename editing. However Windows 11 doesn't have this problem.

Fixed it by treating a missing input handler as not accepting text
input.

## Testing

I've tested on both Vim/Helix mode and normal mode with Vim/Helix
keybinds. All clear now.

ABC...Z character shortcuts are not going to be intercepted by IME
unexpectedly in project panel now.
