Android Studio 3.6.2 multiple project windows cannot add new classes at the same time, while QtCreator is not restricted

When using Android Studio recently, I created a new Java class, but found that this window is a program-level modal, not a window-level modal.
In other words, when I want to operate the new resources of two projects at the same time, I can only close the resource window of one project first, and then open the resource window of the second project.
I verified this on both Android Studio 3.5.2 and 3.6.2.
But in the previous QtCreator, I have never encountered this before, so I will record it.
