Issue
Keyboard control - The content can be loaded, but it cannot be started without using a mouse.
Keyboard control - The controls can only be tabbed through if the mouse is used to show the control bar (therefore, unusable with only the keyboard).
Keyboard trap - Once the user tabs inside the pane, there is no way getting out of the player zone.
Focus order - Focus cannot be made into the player without first clicking into it with a mouse.
