            Bug ID: 26949

                    5 spec

There is a conflict between this restriction

"Dynamically modifying a source element and its attribute when the element is
already inserted in a video or audio element will have no effect. To change
what is playing, just use the src attribute on the media element directly,
possibly making use of the canPlayType() method to pick from amongst available
resources. Generally, manipulating source elements manually after the document
has been parsed is an unnecessarily complicated approach."

and the shadow DOM distributions spec


that results in the video tag not being able to be constructively used inside a
web component
