Copied from Gecko, I believe. Opera does it too. Safari doesn't return true ever, in the test above, so I'm not sure WebKit-based browsers are necessarily a good place to go for checking interop.

bz, do you know if this is required for compat?
Comment 3 Simon Pieters 2012-10-10 07:55:36 UTC 
Chrome returns true for me. Safari as well if I increase the timeouts.
Comment 4 Boris Zbarsky 2012-11-26 16:03:55 UTC 
For web compat, the components of "complete" need to be able to change while script is running.  "complete" itself may not need to change, but it seems to be adding extra complexity to change it async somehow.  In particular, I suspect specifying it would be difficult.
Comment 5 Simon Pieters 2012-11-26 19:15:59 UTC 
Can you elaborate on what components are needed for web compat?
Comment 6 Boris Zbarsky 2012-11-26 20:00:05 UTC 
Primarily entering the "completely available" state.

But the other cases are also somewhat interesting.  If removeAttribute("src") happens on a broken image, should "complete" immediately start returning true as the spec suggests?  It's certainly easier to implement it that way....
Comment 7 Ian 'Hixie' Hickson 2012-12-27 00:25:19 UTC 
zewt says IE9 does the same as WebKit, so we're 50:50.

I'm leaning towards leaving the spec as is unless Opera is planning on changing.
