I haven't looked into this closely to see what styles they're using, but a lot of the text around the form fields on matrix.itasoftware.com is not visible. Screenshot attached.
It works in the latest Aurora, but busted in Nightly.

It's not styles. The text is not present in the DOM either.
All that stuff seems to be script-generated, and they're running into some sort of scripting issue. E.g. see the "undefined" next to the dropdown with 1--9 in it...

fix and test
The bug was that arguments["i"] needs to return arguments[i] (for integers i) and the patch failed to do that when the arguments object had been optimized away (NormalArgumentsObject::optimizedGetElem).
Thanks for reporting Margaret!
