Domain mapping breaking media edit in WP

Hi, we are finding within the last week that domain mapping is causing an issue with the media editing window on our subsites. We are able to insert images with no problem, but if those images are reselected, the edit window that opens in blank. I've gone through every single plugin we have (there are many) and after much hair-pulling, this ended up being the one, the one I was most reluctant to mess with :slight_smile:. Obviously I can't turn it off long term, I'm guessing it is related to a recent update since this has only been a problem recently.
