Description Ian 'Hixie' Hickson 2011-08-26 00:36:40 UTC 
"Copy all attributes of element to replacement element, in order" doesn't say what order.
Comment 1 Ian 'Hixie' Hickson 2011-08-26 00:37:08 UTC 
(Presumably it means the order of the "attributes" array defined in DOM Core?)
Comment 2 Ehsan Akhgari [:ehsan] 2011-08-26 17:04:57 UTC 
I'm having a hard time imagining why the specific order would matter here...
Comment 3 Aryeh Gregor 2011-08-28 15:50:56 UTC 
Attributes definitely have an order.  If DOM Core makes that unclear, it should be fixed.  If Ms2ger's changes in bug 13912 aren't enough, please tell him what he should do to make it clearer.

It's author-visible behavior, therefore it matters.  Apparently the order of *methods in IDLs* has web-compat implications:

https://bugzilla.mozilla.org/show_bug.cgi?id=623437

So the importance of making sure we get element attribute order right should go without saying.  :)
Comment 4 Anne 2016-04-13 09:18:37 UTC 
Per bug 17871 they have a deterministic order, although it will take some time for implementations to converge.
