Bug 198244 – iOS: Main frame should be scrollable when pinch zoomed or software keyboard is up

• Status: RESOLVED
• Resolution: FIXED
• Component: Scrolling

[Ryosuke Niwa]

Even when overflow: hidden is specified on the frame view, we still need to make the main frame scrollable
when the software keyboard is up or the user had pinch zoomed the page.
