Modals/Dialogs are not always-on-top

Specifically, in Valley scenario, poison in auxiliary storeroom.
When I pick it up, the game interface no longer responds although the menus still work. Almost as if the ui-lock from the modal is still in effect.
When I save, the game updates that I picked up the poison, but otherwise still unresponsive.

Just got some sleep and realized that game indeed hadn't crashed, but there was a modal behind the game window. If these can suspend the game UI, they should be always-on-top.
