What happened?

At this moment disabled Buttons are not focusable for blind users. You can overwrite this with the tabIndex but this is not working in the DialogActions.
They should be focusable aswell, so that blind users can get information about the status.
I think there should be a prop to make this possible.

Steps to reproduce the issue

1. disabled button on view
2. try to tab to a button
   you cant tab to the disabled button

Relevant log output

Implementation Details

• Remove tabindex logic for disabled buttons (all types of buttons, but not form elements)
• Add accessibility documentation for button components to recommend adding aria references to describe why the button is disabled (from consumer side)

Quick update: We are considering changing the implementation, but first we need to research the topic not to make it worse.
