    @rekire Thanks for filing the issue. I am not really sure I understood the issue. Do you mean when the input is focused and switched to other apps and the focus stays? Can you please update the reproducible steps.

    When you remove the alignment right part, you can use the arrow keys to move the keyboard focus to the buttons aaa or bbb depending if you press or or down.
