iPad Reset Freeze

[KatieWoe]

For ES6 Testing.
Seen on iPad 13 and 12, but not on Win 10.
When you hit the reset all button the sim freezes. Looking at the console you see an error that reads:

Error: Assertion failed: describedby association already registed

Thanks!

I can use this in correlation with phetsims/chipper#845 to help debug the case

I cannot reproduce this anymore. When I use an iPad all is good with the reset all button. QA, if you cannot reproduce this during the soon-to-come dev test, please close.

[zepumph]

Scratch that. I improved my error handling and I see things clearer now.

[zepumph]

Ok. I did a bit more poking around, and my previous thoughts were a false positive. QA, if you can't reproduce, please close.

[KatieWoe]

Looks ok from what I can see.
