- Focus an enabled, focused button widget.
- Disable the button widget (notice how it still shows the focus outline):
- Try to navigate away to an enabled button (left / right), you can’t!
From that point on anyone without a cursor device is screwed.
Why?
Because the keys you are pressing no longer end up on the button widget, they end up bubbled to the parent, which in this case happens to be a horizontal box.
What does the horizontal box say?
It says scr*w you, I’m not focusable.
Unless we are going to exclude about every system except PC, this is breaking.
Request: Allow navigational keys on disabled focusable widgets such as button.
