This is not resetting on Linux because it allows calling a nonvirtual function with a null this pointer.

If I add this assert statement it will reset on Linux too.
Source/WebCore/page/FrameView.cpp

ASSERT(elt->renderer());
layer = elt->renderer()->enclosingLayer();

The Sample html files to reproduce the crash in 
https://bugs.webkit.org/show_bug.cgi?id=59684 
show a small test case.

We should be able add a layout test now.
