-"""A Telemetry page_action that performs the "play" action on media elements.
-
-Media elements can be specified by a selector argument. If no selector is
-defined then then the action attempts to play the first video element or audio
-element on the page. A selector can also be 'all' to play all media elements.
-
-Other arguments to use are: playing_event_timeout_in_seconds and
-ended_event_timeout_in_seconds, which forces the action to wait until
-playing and ended events get fired respectively.
