Tapping in the empty space to the right of "Custom button 2" should hit the button. Currently, it has no effect.

To fix this:

1. Make the buttons full-width by setting the min and max width in their layout to the full width of the menu (code).
2. Align the text in the button to the left or right depending on the text direction.

Currently, TextButton always centers its child and can't align to the left or right.
