You have oil returning but there is an airlock that is trapping it in a hose or in the box itself.
There will be a pile of foam, and your reservoir will drop as oil replaces air. The danger is dropping it too low and sucking in air again. You may have to repeat this maneuver.
I have had so much foam in one I did last fall, I have had to walk away and come back next morning after it settled down.
Tried it a few times on and off through the day and still doing the same thing I have a feeling something went south of the arctic pole with the power steering pump or Hydra-booster
