Feel free to WONTFIX if you think this modified is too artificial or just plain crazy.

I changed the following:
var RECT_COUNT = 500;

To :
var RECT_COUNT = 50000;

Glenn, what do you think about this? Seems to be an older crash based on the crash reports, but it is nice to have a reproducible testcase for it.

We should definitely fix it, but it can be low priority since it's a very artificial test case.

The fix in https://bugzilla.mozilla.org/show_bug.cgi?id=1746062 also fixes the panic here. We still perform terribly on this test case, but chromium also seems to be just as bad.
