I have a div with overflow:scroll.  If I click in the div with the mouse I can then scroll it up and down using PgUp, PgDn, the up/down arrow keys, and the spacebar for page down.

On the other hand, if I set the focus on the div using focus() from Javascript, then spacebar does nothing while the other keys all continue to work.

It seems to me that there must be more than one sort of "focus", since calling focus causes the focus outline border to be shown, while clicking with the mouse doesn't.

I'd love to know if there is something else that I can do from Javascript that gives the "right kind of focus" so that space works.

I'll attach a test case.

Reproducible: Always

Steps to Reproduce:
1. View the test case that I'm about to attach.
2. Press the button.
3. Press PgUp/PgDn/cursor keys - they work.
4. Press space - nothing happens.
5. Reload the test case.
6. Click in the scrolled box with the mouse.
7. Press the keys again.  Now space does work.
