[LH2586] Page View after effects

When I go View > Text Editing > Page View, the current edit window reformats, changing width and applying a dark gray background to the window. But when it repeat the action, to toggle Page View off, the dark gray background remains and proceeds to show up in other items and windows.

Windows 10 Pro 64 bits, Scrivener beta 2903 64 bit
