In The Last Jedi, after the opening battle, the Resistance makes a jump to hyperspace. Shortly after exiting hyperspace (Spoilers follow),
it is discovered that the First Order has somehow followed them, and another brief battle ensues. This results the Raddus's bridge being destroyed, with many of the highest ranking leaders being blown out into space, killing all but one of them: General Leia. She is able to use the Force to pull herself back to the ship, where she is able to re-enter the bridge and approaches a sealed door. Here, we see that Poe, Finn, and Lieutenant Connix saw her coming, and they opened the door to let her in.
How were they able to open the door without being blown out into space?
