           Summary: [WK2] Cannot go back from page loaded with
                    WKPageLoadAlternateHTMLString
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cgarcia at igalia.com
                CC: andersca at apple.com, sam at webkit.org,

To reproduce:

 1.- load a page with WKPageLoadURL
 2.- load an invalid page and in load error callback load alternate page with WKPageLoadAlternateHTMLString
 3.- load another page with WKPageLoadURL
 4.- WKPageGoBack() -> alternate page is loaded
 5.- WKPageGoBack() -> alternate page is loaded again
.....

So it's not possible to go back from the alternate page. The problem is that FrameLoader::shouldReloadToHandleUnreachableURL() assumes loads happens synchronously, which is true in WebKit1 but not in WebKit2, and for WebKit2 compareDocumentLoader is always NULL and shouldReloadToHandleUnreachableURL() never returns true.
