           Summary: Response time is slow when we select Video content in
                    Youtube/tv
           Product: WebKit
           Version: WebKit Local Build
          Hardware: PC
                OS: Linux
            Status: NEW

Hi, I am facing ~1 second delay when I starts play a content in Youtube/TV.
I can see the delay only when I use debug build. 
In Release build, Video starts playing immediately when I press Enter key.

I tried to debug and found that KeyUP event is sending after 1 sec from WebPage::keyEvent to UI Process.
Somewhere It is blocking/waiting for DOM tree processing.

This issue is only observed in Debug build. Can someone please give your suggestion on this.
