Wall sprites in E4L3 can be passed through when shrunk (inconsistency compared to DOS Duke 1.5)

When the player is shrunk, as of 19c21b9a, he is able to pass through the following wallsprites in E4L3, Shop N' Bag:

Get shrunk by a Newbeast and you can pass through this door in eduke32, while it is impossible to do so in DOS Duke 1.5.

With other wallsprites, passing through is the expected behavior, but the above gates behave in a different manner in the original game.

This is because the sector is originally lowered and raised on start of the map. It appears that the game behaves differently in this situation.
