Release

Students no longer see a tooltip nor any button affordance (i.e. cursor
and color change on hover/focus) on the pinning feature. For moderators,
the tooltip is now correct when a thread is pinned, the button is
accessible for keyboard-only users and screen readers, and an error
dialog now appears if an error occurs in attempting to pin/unpin.

STUD-1140

When there is a start-time:

Initially, the video starts playing from the start-time.
Whenever the player resets for any reason (such as reaching
the end of the video), it will reset to start-time instead of 00:00:00.
It should not be the case that any time the user presses play, it
start playing from start-time.
