Yes...that's a problem for me too

As a workaround, you can listen for iron-activate and check the selection state + close the menu when that happens. Here's a demo.

You can also listen to tap event on the paper-listbox and close the menu http://jsbin.com/fasagi/1/edit?html,output Anyways this issue doesn't belong here, it should go to paper-menu-button as it is the one controlling the close on selection change, so I'll move it there. I believe the current behavior is by design, a selection change should close the dropdown.
