This has never been a supported use-case, there never was any guarantee that it'd work, for as long as I can remember (and I started with GWT 1.4.61; well, actually, I believe at that time having several GWT apps on the same page wasn't even supported). I believe you can find issues about this if you go far enough in the past (see https://github.com/gwtproject/gwt/issues/628 and https://github.com/gwtproject/gwt/issues/592 which seem related, there probably are others) I'm even surprised it could have ever worked. AFAIK, the only situation where this *could* work would be if the two frames/windows load the exact same GWT app code (but execute different code paths in the onModuleLoad based on the URL or some other aspect of the host page). So while there might have been a change in GWT 2.7 related to how type information of objects is represented, it cannot be called a bug or regression.
