Fix a crash caused by touching outdated assigned_nodes

This is a tentative fix for several crashes cluster fuzzer reported.
It looks HTMLSlotElement::DetachLayoutTree is touching dirty
assigned_nodes.

It's still hard to have a minimized test case, so I'll work on that later
to investigate further. I've added TODO comment there.
