Here's what's going on (relevant browser is browser 36).

This load triggers a remoteness change.

This is the load that should actually end up in the browsing context.

From the previous remoteness update.

At this point, we try to use the BFCache, and end up replacing the
browsing context:

So this is certainly the easy fix, but I think we should generally try
to deal with this better, somehow?

…ect> / <embed> as subdocuments. r=longsonr

These look like two really old bugs.

Part of the issue is that <object> / <embed> manage their frame loader quite
differently from <iframe>. This means that we may have a PresShell /
ViewManager / etc for a frame loader that doesn't yet have a frame associated.

For example, this is the viewport creation for the SVG document that reproduces
the problem:

The parent view may not be set properly if the frame is not current by the time
it is created. For example in this case the parent for the root view is
non-null and comes from the following MakeWindow call:

However, even though aContainerView is non-null, the view is incorrect, it's
the view for the _old_ frame.

The view parent/child relationship gets cleared properly in:

But the temporary state is stored in the _old_ frame-loader, so when we create
the new frame, we get to nsSubDocumentFrame::Init, and find nothing, and thus
go through nsFrameLoader::Show. But we do have a pres-shell, and
nsFrameLoader::Show just early-returns then, and thus we end up with a detached
pres shell which is not hooked to the view tree and thus not painted...

So there are multiple potential fixes. First (this is the approach this patch
takes):

 * Make nsHideViewer not fail to hide a presentation when the frame loader
   has changed. This is not an issue per se, but leaves stale views / etc
   living for too long which is not nice.

 * Fix up the Show() code path to handle this case properly by parenting the
   pres-shell and initializing the docshell properly.

Second potential fix would be to store the temporary state somewhere else than
the frame loader (like the element). This may be a less invasive change
somehow, but it looks pretty fishy to me, and not particularly better...

Terribly sorry about the lack of test-case, but this is racy as crazy and I had
a lot of trouble to even reproduce it in a debug build. This needs the
PresShell creation for the subdocument to happen right after setting .data on
the <object>, but before processing its reframe.
