Test device: IOS 13.0 Beta 4 (17A5547d) on iPad Pro 10.5-inch (MPMF2NF/A). Adding the overflow:hidden property to the body of a page blocks scrolling in any PDF file opened from that page. Minimal reproduction scenario: Given the following html page: <html> <head> </head> <body style="overflow:hidden;"> <a href='/test.pdf'>Open me</a> </body> </html> When clicking on "Open me" opens the PDF file but the user can't scroll in it. It remains stuck at the top of the document. Expected behavior: The PDF file is scroll-able as works on desktop.

Uh oh.
- (void)_setHasCustomContentView:loadedMIMEType: needs to reset the scrollability bit
