It looks like this is happening in mozilla::RestyleManager::DoProcessPendingRestyles. Given the other log spew happening before the assertion, I suspect this test is leaking, and this assertion is a side effect of a leak.

What makes you think that? AFAICT there's only a non-fatal assertion in DoProcessPendingRestyles due to some JS code that is still running and calls into getBoundingClientRects().
But seems unlikely that the leak comes from the style system. The issue is the JS code that's calling into it after shutdown, which is presumably what leaks.

I think there's a leak because there's a bunch of log spam like this:
ERROR: GC found live SharedScriptData 0x7f2facbe6ac0 with ref count 2 at shutdown
Yeah, it doesn't seem likely that the leak is due to the style system, but it is hard to say without more evidence one way or the other.
The oranges are all in the mochitest-devtools-chrome-sw-e10s-10 test suite, whatever that is.
