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. 1558452 1 webkit-bug-importer 2019-08-05 08:21:38 -0700 <rdar://problem/53942888> 1558496 2 simon.fraser 2019-08-05 11:36:26 -0700 Uh oh. 1558507 3 thorton 2019-08-05 12:26:16 -0700 - (void)_setHasCustomContentView:loadedMIMEType: needs to reset the scrollability bit 1558574 4 375564 simon.fraser 2019-08-05 15:06:48 -0700 Created attachment 375564 Patch 1558650 5 375564 commit-queue 2019-08-05 17:32:04 -0700 Comment on attachment 375564 Patch Clearing flags on attachment: 375564 Committed r248281: <https://trac.webkit.org/changeset/248281> 1558651 6 commit-queue 2019-08-05 17:32:05 -0700 All reviewed patches have been landed.
