- Set a Toolwindow on auto-hide at the right side of the Docksite
- Mouse over the Toolwindow to display it
- Open the ToolWindow menu (Float, Dock and etc...)
In the last step, if the user isn't fast enough, the opening Menu will make the auto-hide ToolWindow hide again, probably because the mouse cursor isn't directly over the toolwindow anymore. It is probably because the menu disturbs the hit-testing.
I expect the toolwindow to not hide when opening the menu.
