There is another issue in setting start time procedure.

2. Unless player has a pending pause task, set player’s start time to new
start time.

According this step player's start time should be set even player has no
timeline associated. But definition of start time is "A player’s start
time is the time value of its timeline". So there should not be start time
without timeline.

Setting start time procedure should catch this case.
