Friendship, comrades!

Here I am now reporting something which IMHO is not really worth fixing, but should it ever bite then I can claim to have reported it first.

BTW, Firefox bug report 652442 is about reporting this correctly when JS is generally disabled and was fixed on trunk just recently.
Using the testcase (cross-domain?) in an img element (in this case scripts are not invoked) shows it correctly (on latest nightly):
