           Summary: REGRESSION (r61285): Page content is partially blank
                    with HTML5 parser enabled
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.6
            Status: NEW
          Keywords: InRadar, Regression
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

In <rdar://problem/8228000> it was reported to us that an internal Apple site displays as an almost empty page with the HTML5 parser enabled.  This happens because the page contains markup similar to the following:

    <script src="data:text/javascript," type="text/javascript" />
    <p>Hello world</p>

In Safari 5 this displays as “Hello world”.  In tip of tree this displays as a blank page.

I understand that this markup is not well-formed due the missing closing tag on the script element, but this seems to be a change in behavior that could have a serious backwards-compatibility impact on existing WebKit-only content.
