If you want this, take it. If not, pass the buck!

I can take this if we bump the milestone to 6.4.5 otherwise please reassign.

This one is involved...I'll need to let it stir in my mind a little bit. Did quite a bit of analysis on it already and I have an idea of what needs to be done.

Is this still reproducible?

Yes, the bug is still reproducible , but the image added at step 4 is now a blank image. Please see the attached screenshot.
