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 snapple.com. See https://bugzilla.mozilla.org/show_bug.cgi?id=599584

Please adjust the spec accordingly to ignore pragmas from innerHTML and from script-created metas.

http://software.hixie.ch/utilities/js/live-dom-viewer/saved/666 doesn't navigate in Gecko, WebKit or IE8 (but navigates in Opera).
Comment 1 Ian 'Hixie' Hickson 2010-10-13 10:10:58 UTC 
Seems to navigate in Chrome, FWIW.
Comment 2 Boris Zbarsky 2010-10-13 15:24:39 UTC 
Note that the URI in the mozilla bug (which uses innerHTML sets) doesn't...

The equivalent testcase is http://software.hixie.ch/utilities/js/live-dom-viewer/saved/669

That test has a scripting bug. This is the equivalent without it:
http://software.hixie.ch/utilities/js/live-dom-viewer/saved/734

It still navigates in Chrome and Opera. Safari and IE seem to prevent innerHTML changes to <head>, which I didn't expect and don't quite understand (especially in the case of Safari... isn't that the same code as Chrome?).

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 snapple.com site. Could you be more specific about how to reproduce the bug? Why does the page not break in Chrome or Opera?
