New issue 443814 by rennie.d...@gmail.com: HTML object and embed tags don't
load inside SVG foreignObject
https://code.google.com/p/chromium/issues/detail?id=443814

UserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML,
like Gecko) Chrome/39.0.2171.95 Safari/537.36

Example URL:

Steps to reproduce the problem:
1. Serve the web pages in the attached archive using the given Apache
configuration.
2. Load http://dom1.chrome-iframe-foreignobject.test

What is the expected behavior?

What went wrong?
The page in the attached archive attempts to load SVGs inside both
sandboxed and normal iframes. The SVGs contain foreignObject blocks
containing XHTML, which tries to load another SVG using img, object, embed,
and iframe tags. All documents are loaded from the same source under
default security policies. This is not a recursive document scenario; the
nested SVG is a different document.

In all cases, the nested document should load, resulting in a circle with a
wart on its lower-right corner. However, recent versions of Chrome do not
render the nested document when it is loaded via object or embed tags. It
/does/ load the nested document through img and iframe tags.

Current versions of Firefox load the document correctly in all cases.
Internet Explorer doesn't render the contents of svg:foreignObject
(including the most recent preview release), so it never renders the nested
images. Old versions of Chrome (such as 27.0.1453.93) do load all of the
cases correctly, so this is a regression in Chrome.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No

Did this work before? Yes It worked in 27.0.1453.93. I don't know when it
stopped working.

Does this work in other browsers? Yes

Chrome version: 39.0.2171.95 Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version:

I also verified this issue on the latest Chrome Canary build on Windows.

rennie@, thanks for the issue. Would you mind attach screenshots of
expected result and the actual(problem) to help us triage better.

The bug seems to have been introduced in build 244510; build 244448 shows
the expected behaviour, but 244510 doesn't.

Sure; here are screenshots from Chromium 39.0.2171.65 and Firefox 34.0 on
my Kubuntu system. In Firefox, the nested images load in all eight cases
(although they aren't positioned or scaled properly in the cases where the
nested image is loaded as an iframe; I'm not sure if that's my fault or
theirs). In Chrome, the nested images aren't loaded at all when using
object or embed tags inside a sandboxed iframe.

I'm reminded of issue 368705...

@rennie: Sure it was 34.0.1783.0 and not 34.0.1784.0? Could have been

Mike, could you have a look?

The referenced change moves the plugin content loadable check from
HTMLPluginElement::loadPlugin to HTMLPluginElement::requestPlugin. Further
investigation is required, but it is certainly plausible that it changed
the behavior of SVG in some way of SVG calls requestPlugin but not
loadPlugin. I'll own it.
