  [Site-Isolation] Fix localFrame to remoteFrame synchronization
https://bugs.webkit.org/show_bug.cgi?id=306904
rdar://169568732

Reviewed by Simon Fraser.

Page::syncLocalFrameToRemote was incorrectly mapping over the child frames. It 
was calling FrameTree::traverseNextSkippingChildren
instead of FrameTree::nextSibling, which caused 
ASSERT(child.tree().parent()->frameID() == m_frame->frameID()) to fail in
LocalFrameView::visibleRectOfChild.
