Input's clear button is not keyboard accessible

[stereobooster]

We can focus it, but it doesn't respond to Space or Enter.

I also wonder do we need it to be focusable in first place - imagine keyboard user - to clear they can do following:

• Ctrl + A, Delete
• Tab (to focus clear button), Space

So what the sense of having clear button focusable, if it the same number of keystrokes.

And after clicking clear button it disappears and kind of hides where focus is (but Shift + Tab will bring it to input).
