[4.0b1 BUG] First item in rom contents list automatically selected/deselected

[Wanderer]

1. Load a database.
2. Click in the roms list (left grid).
3. Start pressing the keydown with a rate of 1 keydown / 1-2 seconds.

Notice that on the 1st keydown, the first item in the rom contents list is selected, on the 2nd keydown is de-selected, on the 3rd is selected again and so on...

I guess it should always stay selected so when the user presses TAB, there will be always something selected.
