Thanks @CWilson4960, this is weird. I am unable to reproduce with Windows 10 Firefox 56.0.2.

Use the arrow keys to navigate the focus box up to the Area slider, or length slider, or resistivity one

How are you able to do this? Do you have custom settings to enable navigation with arrow keys? Or were you by chance using a screen reader prior to testing?

I just tried to reproduce with Hanson testing machine, when I turned volume on NVDA started talking to me, so the screen reader was enabled. When I turn the screen reader off, the problem goes away. I can no longer use the arrow keys to move focus. Closing.

Thank you Jesse! Sorry I didn't catch that! I hope it wasn't too much of an inconvenience.

Not at all, it was definitely more of an inconvenience for you, I was most likely the last one who left it on. Sorry about that!
