Keyboard help button highlighted upon loading sim

[ghost]

Test device:

Hanson

Operating System:

Windows 10

Browser:

Firefox ESR 52.6.0

Problem description:

@jessegreenberg I noticed that upon loading the sim with NVDA running, the keyboard help button is highlighted in the usual pink/purple color to indicate keyboard navigation. I didn't press any buttons or click anything with the mouse. Related to phetsims/QA/issues/108.

EDIT: This can happen with anything you can tab to, not just the keyboard help button.

Steps to reproduce:

1. Start NVDA.
2. Tab to something.
3. Reload the sim. (The sim should load with the thing you tabbed to highlighted.)

Seems to be isolated to FF ESR (can't reproduce in Chrome). Checking to see if it happens with FF Quantum.

Sorry @lmulhall-phet I should have let you know about this - this is a screen reader feature not a but. Screen readers (especially NVDA) will try to remember the last thing that had focus and restore it on page and return focus to it on page load. I will make a note of it in the testing template.

Ah, I was wondering if it was a feature... It seems too convenient to be a bug. Thanks @jessegreenberg.

I made a note for next time. Closing this issue, thanks @lmulhall-phet.
