Gecko does this too (I think starting in Firefox 3.5?), but we got
quite a few complaints about it, and I'd like to change it.

It has the significant disadvantage that the relationships between
colors in different parts of the same page can be different
depending on the device (when a page has both tagged images and
other colors).

I think we should move towards treating CSS colors (and untagged
images) as sRGB, as CSS1, CSS2.1, and css3-color require.
