Not sure if it's a valid bug, anyway: Regression range: good=2014-07-11 bad=2014-07-12 http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=e1a037c085d1&tochange=b0701d069bf9 suspected bug: Gijs Kruitbosch — Bug 577892 - allow icons to change when href attribute is set directly, with automated test, r=dolske,bz
I expect this is an actual regression, yes. Redirecting to bz to be sure.

Yeah. We should probably not fire DOMLinkChanged for <link>s that are not in the DOM.
Like this? Note that I've not tried to actually think hard about shadow DOM or any other edge cases... I don't think there are any? But then, the name 'IsInUncomposedDoc' is not very clear and so I'm not sure if this should change the result here...

Comment on attachment 8506345 [details] [diff] [review] favicon should not change if link element isn't in DOM, I think this is what you want, yes. IsInUncomposedDoc() means "in document, not in shadow DOM". Naming is hard; we spent about a week trying to come up with good names for this stuff. :(
