fix: Make.IsOpen() in the world switcher (#77)

The make menu was coming up as true in the world switcher.
Not a big deal but I added some width and height limits to stop it from happening.

I don't know exactly what's the true upper limits because they vary from task to task and I can't try them all so I set it to something that felt reasonable.

Also removed the second loop of the method which wasn't required at all
