WKWebView snapshots have the wrong scale after rotation
Created attachment 255865 [details]
There are still a lot of weird edge cases with the snapshotting timing, so I'm going to look into having the software snapshot case go through the remote layer tree commit mechanism so that we always get the "right" answer, but if that doesn't work out this patch fixes one of the many bugs.
