When spectating, if I highlight or select any unit (single or multiple) my camera settings automatically start tracking that player's camera.
If I sit idle long enough, it will also just randomly start tracking a player camera.
Pressing the Player Camera button above scoreboard will stop following that player's camera, but sometimes does not restore my camera control setting back to 'overhead' from 'spring'
Sometimes there is a delay of a few seconds from the time I select a unit to the time it starts following the player's camera
