Handle a disconnected view during applyTopLeftLocationOffset
https://bugs.webkit.org/show_bug.cgi?id=241355
<rdar://92432637>
Reviewed by Alan Bujtas.
It appears that we can sometimes end up in a state where the document's
view is disconnected during didLayout, which calls applyTopleftLocationOffset.
This just adds a null check to handle this case for now.
