Same old story, the overlay on the widgets in a content page blocks access to the menus that are inside the content of the widgets.
1) Add a content page, add an asset publisher widget
2) Can use cog icon to configure the widget
3) That same overlay blocks access to the widget itself which contains other menus
Change how this overlay is positioned. For example here setting a width of 50px stops the overlay from blocking the widget menus.
