When a I click my popup button, it shows NSMenu.PopupMenu correctly.
But when I hide and show up again my button and click, it does not show menu anymore.
My popup button belongs to a StoryBoard/ViewController which is loaded via ContainerView(segue) in other VewController.
When I click outside of the main Storyboard/ViewController space and click my button then popup menu shows up again.
My popup button has a height constraint and belongs to a StackView as well.
