Navigating a playlist broken in 3.4.0 - video does not render

Attempting to navigate a playlist by clicking the next item results in a blank screen. The audio still plays, but the video does not.

Exiting the stream by clicking the X next to the stream, results in the preview of the video stream appearing at the bottom. Clicking on the preview does result in the video then playing correctly.

This worked fine in the previous release.
