Falling through the floor after going through doors and closing them

Hi, I'm having an issue of when i sometimes open and go through doors quickly and then close them, i sometimes fall through the floor and take suffocating damage. It doesnt really annoy me that much, but it might be annoying to other players is my concern, so please fix this if it isnt too much of a problem.

 

Thank you and have a nice day
