fix: keyboard navigation breaking

[JammingBen]

Description

Fixes the keyboard navigation breaking in certain scenarios.

The issue was that window.getSelection() would not always return the currently focused element when checking if we need to disable our custom keybindings. So e.g. when clicking the search input and then clicking a file in the file list, the focused element would still be the search input, leading to our keybindings not working.
