           Summary: [Chromium] Support adding/removing page overlay to
                    WebView
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs

Background dimming when a tab modal dialog shows up does not work when WebKit accelerated compositing is on (http://crbug.com/103386). The best way to fix the problem across platforms would probably be implementing the dimming as a PageOverlay (introduced in https://bugs.webkit.org/show_bug.cgi?id=62149). To do that, we need to support multiple page overlays in WebViewImpl and open an API to add/remove page overlays.
