142702 2015-03-14 16:39:25 -0700 [iOS] Presenting a modal sheet on top of a WKWebView causes it to lose focused, active state 2015-03-16 05:16:44 -0700 1 1 1 Unclassified WebKit WebKit2 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 1 mitz mitz andersca ddkilzer sam thorton oldest_to_newest 1077187 0 mitz 2015-03-14 16:39:25 -0700 When a view controller is presented modally on top of a WKWebView, the web view is removed from the view hierarchy. This causes it to resign first responder status, and to signal the DOM that it is no longer in an active, focused window. In particular, this will cause any focused input element to lose focus. The result is that, for example, when focusing a credit card number field on a webpage and using Safari to capture credit card information from the camera, which involves a modal sheet, the field is no longer focused after dismissing the sheet. 1077188 1 248658 mitz 2015-03-14 16:46:36 -0700 Created attachment 248658 Add -[WKWebView _retainActiveFocusedState] 1077253 2 248658 andersca 2015-03-15 12:27:32 -0700 Comment on attachment 248658 Add -[WKWebView _retainActiveFocusedState] View in context: https://bugs.webkit.org/attachment.cgi?id=248658&action=review > Source/WebKit2/UIProcess/API/Cocoa/WKWebView.mm:1779 > +- (void (^)(void))_retainActiveFocusedState I really think we need a name here that indicates that this returns a block.
