Yes, i got the assertion in EFL debug build.

> This is a wrong fix. The problem here is that we're calling child.document().nodeWillBeRemoved after the node had already been removed in willRemoveChild (ContainerNode.cpp). What we need to do instead is for every call site of dispatchChildRemovalEvents to check whether the mutation events had removed the parent, and avoid calling Document::nodeWillBeRemoved if they did.

I'm trying to fix this in that way.
