Hello,
I had this gadget enabled for quite some time, but after various issues have finally bitten the bullet and disabled it. The last straw was one particular issue that I hope is just a bug: a user on English Wikipedia had gone through and inexplicably removed most line breaks. They'd made several other changes I didn't want to revert, so I couldn't just revert the entire edit, so I bothered to go back and add in all the removed line breaks by hand. This user by then had made yet another edit, so the edit conflict window came up. Despite clicking on "my side" for each option, it didn't matter - all those line breaks I re-added were thrown away. That can't have been intended behavior. Hopefully this suffices as reproduction steps, but is this fixable? I would link the edit in question but get an "abusefilter warning linkspam" when I do so...
