A user can set their "Prefer tabs" preference for opening documents to "Always" (rather than the default "in full screen") on either 10.15 or 11.0, and then all top level windows will open up in a tab unless they are child (owned) windows.

Yes, I have tested that.

All above are applicable to any applications and all frames/dialogs on the new macOS. For some reason, Apple decided this can be a good design. Why we do not try to fit in it? 
 - We may try to configure the correct size when a few windows are merged to the same window
 - We may try to fix a "hang" of some type of the windows
 - And we may try to disable it for some type of the windows by creating "fake" owner.
