           Summary: IFrame resize feedback loop on iPad
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: iOS
        OS/Version: iOS 7.0
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Frames
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: alex at lagoa.com


Steps to reproduce the problem:
1. Go to the fiddle at http://jsfiddle.net/6gVAX/ on an iPad running iOS 7.1.1 in Safari (or Chrome).

This fiddle is just an iframe containing another fiddle. The sub-fiddle is merely a binding on the window's resize event, which will show an alert with the window's innerWidth and innerHeight values.

What is the expected behavior?
The fiddle should show an alert only when the preview frame resizes. This is what we observe on OS X 10.7.5 running Chrome 34.0.1847.137.

What went wrong?
The fiddle shows an alert again and again, seemingly without end. The message shows the width and height of the window object in that iframe, and we can see that the height continues to increase.

This was also reported to the Chromium team (https://code.google.com/p/chromium/issues/detail?id=379847).
