Comment (by sluicebox):

 Script patch: https://github.com/scummvm/scummvm/pull/1427

 This bug is indeed due to differences in the pathfinding algorithms that
 let Laura reach one pixel further in ScummVM and trigger a room change. I
 worked around this by expanding the closed door's polygon by one pixel to
 prevent this.

 This is a game-breaking bug as there's no way to return from the crate
 room the way you came. The crate room doorway isn't wired up to anything
 since you're not allowed to go backwards during act 5 chase.
