Edit movie clip in place bug

When trying to edit movie clip on place, program opens it in a new tab hiding all the background, duplicating other editing option. I just need it old good way when I can see it on same stage seeing other objects.

I have asked support, they were not very good in this part of the program and told me this is the way it works now. But today after I published this issue half an hour ago and it started working the way I want, so this is a bug.. But now it started working wrong same magical way as it was fixed ( I did not find any switch option or click anything that may be connected to movie clip life :).

So I know now this is ф игп as it may all of a sudden start working well and then break again for no visible reason. Is there a way to make it stable and work old way? Or can it be fixed further? Or what should I do to make it behave usual way...
