I was just wondering if portals don't close until someone goes through - or are they open for a certain amount of time and then close regardless??

I just seems that they only close after someone's gone through - Bae in the EF, Neal in LWM (hmmm, maybe it's just him then ha ha)!! The hat started closing after Emma went through and MM only just made it. I realise that the majority of the times the portal's been opened on purpose as someone/something needed to go through but the one Tamara opened didn't so it just got me thinking!
