What if you put something in the normal bag space while in the Anti-Magic Field? What happens when you leave and the bag accessed extradimensional space again?
Interesting. I think the item would fall through into extradimensional space when you next opened (use-activated) the bag outside the antimagic field. If the extra dimensions were already filled to capacity then the bag would rip when opened.
