Description Henri Sivonen 2010-10-12 13:20:02 UTC
The old parser in Gecko didn't honor the semantics of <meta http-equiv> coming from innerHTML. E.g. not honoring http-equiv="Refresh" is required for compat with See

Please adjust the spec accordingly to ignore pragmas from innerHTML and from script-created metas. doesn't navigate in Gecko, WebKit or IE8 (but navigates in Opera).

Seems to navigate in Chrome, FWIW.
Comment 2 Boris Zbarsky 2010-10-13 15:24:39 UTC

Status: Rejected
Change Description: no spec change
Rationale: Opera and Chrome do what the spec says. Safari and IE seem to just not allow innerHTML to change on <head>. Based on this, I haven't changed the spec here.

I also had trouble finding the problem on the site. Could you be more specific about how to reproduce the bug? Why does the page not break in Chrome or Opera?
