Bug 154936 – HTML parser an element inside a template element in a browsing-context-less document with a wrong owner document

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

[Ryosuke Niwa]

HTML parser should not be instantiating the custom elements inside a template element using the containing document's registry.

Instead, it should be using the registry of the inert template document:

I don't think we should diverge from upstream. If the test is wrong, we need to do a pull-request and re-sync the tests. I would land any change here that has not landed yet upstream.

Sorry, this patch was meant for the bug 148850 :(

The patch didn't fix custom elements at all. Will file a new bug to track that.
