Just tested with FF 4b6 on Mac 10.5 and the selected image does not turn white. Is this a recent regression?

If I do the STRs in a current SeaMonkey debug build I get lots of those warnings:

WARNING: Someone passed native anonymous content directly into frame construction.  Stop doing that!: file /home/i6stud/sibresch/nobackup/seamonkey_hg/trees/comm-central/mozilla/layout/base/nsCSSFrameConstructor.cpp, line 6006

Confirmed on Linux x86_64 as well.

Works in: Mozilla/5.0 (X11; Linux x86_64; rv:2.0b6pre) Gecko/20100909 Firefox/4.0b6pre (buildID = 20100909030732)

Broken in: Mozilla/5.0 (X11; Linux x86_64; rv:2.0b6pre) Gecko/20100910 Firefox/4.0b6pre (buildID = 20100910030851)

The two closest archived nightly builds I could find for my platform.

Using about:buildconfig in the nightlies gives this regression range.

I'm bisecting the range...

Landing of changeset 0aa1272e932f of Bug 485501 causes the problem.

Heh, I just finished bisecting and saw your comment!  And that's totally true.

Tentatively assigning to dbaron.

Bug 599368 should technically be marked as a dupe of this one, but since that bug is marked as a blocker, I'm marking this as a dupe of bug 599368.
