            Bug ID: 190260
           Summary: [iOS] Pressing space bar outside editable content is
                    handled twice
           Product: WebKit
           Version: WebKit Local Build
          Hardware: iPhone / iPad
                OS: iOS 12
            Status: NEW
          Severity: Normal
          Priority: P2

Using a debugger, perform the following:

1. Set a breakpoint at <https://trac.webkit.org/browser/trunk/Source/WebKit/UIProcess/ios/WKContentViewInteraction.mm?rev=236303#L3125>, have it log "%B" and continue automatically.

2. Set a breakpoint at <https://trac.webkit.org/browser/trunk/Source/WebKit/UIProcess/ios/WKContentViewInteraction.mm?rev=236303#L3731>, have it log "%B keyDown: @event._isKeyDown@" and continue automatically.

3. Set a breakpoint at <https://trac.webkit.org/browser/trunk/Source/WebKit/UIProcess/ios/WKContentViewInteraction.mm?rev=236303#L3742>, have it log "%B Skipping" and continue automatically.

4. Launch MobileSafari, visit nytimes.com and let it completely load.

5. Press and hold the space bar for a few seconds.

I see the following debugger output:
