FWIW, I use IntelliJ and can reproduce this bug as follows:
1. Open up any project
2. Click and drag a file in the left-hand navigation panel, as if to move it to some other location
3. At some point during the dragging process, the menu bar pops out - despite the mouse going nowhere near the screen edge - and stays open until post #4's workaround resolves it.
I've attached a small video of the problem, hope it helps
