Tested on FF55 with a clean profile and found the same result(no back to black) as with following versions of FF.
It seems the same on Safari and Chrome. Tim, could you confirm again?

It does not happen on Chrome.

Also, it would happen to anything draggable, not just images. I can reproduce this by dragging a link.

I am sorry, I was wrong. This happens on Fx55 as well. I still wonder if this is a regression though.

I am not sure this is a regression because I tested this issue with the following test data URL https://www.w3schools.com/code/tryit.asp?filename=FJW8SJADA8UV and it is reproducible on older Nightly versions, such as 8.0a1 (2011-08-01).
