This is about dragging a tab out of or into a browser window, and letting the compositor know about it, so it can move and place the window accordingly. Apps don’t get to place windows themselves.
I used to do apps with QT (as well as with Java) and when creating a window, I only needed to say, “new window of that preferred size please”, then the engine would make the window of that size if possible.
Now, maybe QT did things more in depth behind the scene, I don’t know.
I don’t understand what is the point of this. Isn’t it the job of the WM to position windows and stuff? Apps have to do it themself now?

How can a window manager position things if the program doesn’t communicate with it correctly?

If Qt or Java is doing it, then that’s still your program and not the WM, though?
I kind of think that’s QTs whole deal right? An abstraction layer that allows for devs to not get stuck in the weeds implementing it all manually.
