What problem does this solve or what need does it fill?
Got stuck recently trying to test some bug fixes for the accessibility module using the button example. I assumed it would work with a screen reader because the example's button entity has the Button marker that the accessibility module queries for. But that isn't the case, for a UI entity to be recognised by the accessibility systems it also has to be the InputFocus.
It's the most basic UI interaction example that a lot of users copy into their own projects, so I think it's essential that it supports the accessibility features.
What solution would you like?
For now, set InputFocus on the button so that the example works with screen readers.
