Exiting keyboard navigation unhighlights keyboard navigation button

[ghost]

Win 10 / Edge: Pressing enter when exiting the keyboard navigation help dialogue unhighlights the keyboard navigation button. Seen on Hanson. Related to phetsims/qa/issues/108.

EDIT: Same thing with space bar.

Interesting note: it actually briefly re-highlights the keyboard help button after exiting the help dialog but un-highlights it immediately after. The keyboard navigation is then completely reset to the starting position in the sim, which appears to be the resistivity slider.

I isolated that this is caused by phetsims/scenery@65a1f08 for phetsims/a11y-research#30. Since I added this work around, Ill try to fix this issue.

I believe this is fixed with the above commit. Release branch will need a release branch for scenery with the cherry-picked commit phetsims/scenery@d27f846

Fixed! Closing.
