Created attachment 472767 [details] Test page In a WKWebView (that has WKPreferences.elementFullscreenEnabled = YES), calling requestFullscreen can trigger spurious and incorrect window.screen.orientation.onchange events. Steps to reproduce (in plain-WKWebView or Chrome on iOS, but not in Safari): 1. Rotate iPad to landscape 2. Call requestFullscreen on some element Expected result: no orientation change events Actual result: We get a sequence of orientation change events: portrait-primary landscape-secondary portrait-primary landscape-secondary I've also attached a test page (from crbug.com/370696600) that demonstrates the bug. Make sure to start in landscape. The bug doesn't repro in portrait.
