Companions open closed doors

[bilal_bravo]

Sorry if this has already been posted/brought to attention but I am trying to be as stealthy as possible but whenever I enter a confined locked space, the companions often lag behind and then open the door on their way in.

I have lost count how many times i had to either close the door or reload a save because I got caught stealing or caused an alarm for hitting someone and the NPC saw/heard me due to the doors being opened.
