The focused element should always be visible

Testing #2145

In this case, I have resized the viewlet area in such a way that the Start (F5) button is pushed out of the viewport. The button should not be focusable if it is not visible, alternatively the viewlet area should have a different min-width when the debug viewlet is open or the debug viewlet should get a horiz. scrollbar.

Steps: Shift-tab a lot => you will no longer see the active element once you reach the Start (F5) button.

I wonder if this is a requirement. For example I have tested on Windows, tabbing into a tree where the focused element is not visible and I do not see the element scroll into view. @stevencl maybe you know the answer here.

Yeah, it would also be pretty hard to implement this given we support zoom in like this:

So it's ok with me to close :)

I don't know the answer in terms of accessibility. It does feel odd that a button can be focusable if it is not visible.

For the specific scenario listed above I think we should consider other ways to deal with command placement when resizing the viewlet. But that is for another bug.
