631547 - Block layout on non-parser-inserted stylesheets too

Status: NEW

(Core :: DOM: Core & HTML, defect, P3)

Description

[Boris Zbarsky [:bzbarsky]]

See bug 629366 comment 5.  We should really block layout start (but not script execution, imo) on non-parser-inserted stylesheets.

Objections?

Taking, but if someone (sicking?) wants to steal, please do!

On a related note, I noticed that setting innerHTML = "<link rel=stylesheet ...>" adds execute blockers to the script loader. Is that intentional? Looks like a bug to me.

Yeah, that's a bug.  Did that use to happen with the pre-html5 parser?

I believe so (at least for XML; didn't thoroughly verify for text/html yet).

Not actively.

Emilio has been looking into some related issues, I think...

I can take a look at this when I have the time I guess, thanks for CCing Boris :)

Attachment: test-case

I haven't seen this come up in practice lately at least. Other browsers don't seem to do this either, but here's a test-case anyways.
