Input Map settings "Filter by Event" input prevents navigating the UI with the keyboard

Problem

In Project Settings, under the Input Map tab, the second input is a box labeled Filter by Event which when focused, records any button presses to be used to filter the input list.

If you try to navigate through the screen using a keyboard, as soon as you pass that input, it starts capturing all keyboard inputs, recording and listing the Tab or Arrow key button presses and preventing you from navigating through the screen with the keyboard anymore.

This is both an accessibility and QOL problem, as it makes it effectively impossible to edit this part of the settings by keyboard only.

Suggestion

Ideally, you would need to press Enter or something to initiate using the box, at least if focused by keyboard and not the mouse, and ideally there would also be some way to escape the keyboard capture using only the keyboard, like holding Escape for a second, or something like that.

What I'd do is the following:

• Ignore Tab and Shift + Tab in the input filter and editing dialog.
• Make pressing Escape close the input filter and editing dialog if the current key is Escape already (in other words, press Escape twice to close the dialog).
• Arrow keys should still be listened to, as they don't move UI focus when on a text field and you can't actually write text in those text fields, so there is no text to navigate within.

Additionally, I noticed you can't tab to the Close button of the project settings dialog (nor the Accept/Cancel buttons of the input editing dialog). We should fix this so that dialogs are fully usable on a keyboard again. (It works in Godot 3.5.3 but not 4.3.)
