I just want to bump again this issue to bring devs attention to it. This bug makes it impossible to migrate to 5.2. Moreover, i did some more research and this bug has its origins all the way in 3.6. I just found an issue HHH-5712 Closed , which was bulk closed before 4.x. It contained the patch that seems will still be applicable to 5.2 branch to fix this issue and make it possible for many of us to use the latest stable release. As of now I'm still stuck with 5.1. Please consider including the fix in the next release.
