Current Behavior

Application crashes when clicking on full screen button while a popup of media element is visible.

Expected Behavior

Not sure. What do we want to do when we have created a popup with mediaElement when it is also in the background behind it? Do we want to remove the full screen button so it is not clickable when a popup is present? Not sure how we would do that off the top of my head. We would have to detect a popup becoming active and then hiding the full screen button? Maybe a solution?

Steps To Reproduce

Build and run the sample app.
Navigate to Media Element Page.
Click on popup.
Click on full screen button.

It looks like this is a weird edge case where it is possible to crash the app by clicking on a button. Full screen button should not be visible and also disabled while a popup is present. Or rewritten to handle full screen switch if popup is present.
