Can't click on paper-item in context-menu on grid

I have the context menu opening up on right-click on a vaadin-grid.

The the paper-items in the list box are not responding to being clicked on. I have tried on-tap and on-click. When I click with the mouse anywhere in the context menu it just closes the menu before registering the item clicked on.

Do Something

Any idea of where to start? What are the issues at play?
