AI2Thor interface doesn't update until the next action is executed

Hello,

I'm running a simple Python script where I'm showcasing how to interact with AI2Thor via the `Controller` class. However, I noticed that the graphical interface on my Mac doesn't update as a result of a given action. For instance, if I execute `Pickup(mug)`, I don't see the mug in the inventory until I execute the next action (say `MoveBackward`). I have also tried with `forceAction=True` but that doesn't seem to make any difference.

I'm using the latest version available via pip. Is there anything that I can do to fix this?
