Comment on attachment 539560 [details] [diff] [review] patch Why is mNextBinding needed? Leaving just those pointers should never create a cycle unless we have some really horrible bugs. r=me if you explain why that's unlinked.
mNextBinding may have mContent pointing to element which keeps document alive.
Though, ofc mNextBinding should unlink its mContent. But still, I'd like to keep unlinking "complete" when possible.
But that gets unlinked, right?
