Flatulent dupes should not expell gas when in atmosuit

After waiting a loooong time, it's sometimes kind of annoying to see a vacuum zone gets natural gas after a flatulent duplicant in atmosuit comes by.

This zone was finally emptied. But when I order to close the small room on the right, Stinky comes to deliver materials and ... well ... he ruins all the work. -_-

Honestly, atmosuit should stock all expelled gases such as natural gas and carbon dioxid, and empty it once docked. At least, in the basement of my base, I have a pump to filter these gases.
