Comment on attachment 404900 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=404900&action=review Sbould make sure that a page that goes into the page cache with an active scroll comes out of it without one, probably? > Source/WebKit/Shared/RemoteLayerTree/RemoteScrollingUIState.h:50 > + RemoteScrollingUIState() = default; Isn't this line needless?
