I would prefer having that in Page to prevent the recursion but I'm not an owner
so I will let the owner decide.

when iterating over the tree and dispatching events, please first copy the tree
to a Vector<RefPtr<LocalFrame> > and then iterate over that as JS might change
the tree structure.

Good point, sorry I missed that. I fixed it.
