Map selection arrow controls

Hello,

In the map selection menu, while having the game name text input focused, the arrow keys still influence the map picker.

Observed on: 1.33.0.19308

Expected:
While the game name text input is focused, arrow key events should only affect itself, i.e., using the left arrow key moves the cursor one to the left, the right arrow key moves it one to the right.

Actual:
The arrow key events not only affect the text input, but also the map picker.
Using the up key changes the map selection one entry upwards if not already at the top.
Using the down key changes the map selection one entry downwards if not already at the bottom.
Using the left key goes one level upwards in the folder structure if not already in the root.
Using the right key goes one level downwards in the folder structure if a folder was selected.
