I'm short

Not sure I understand how your mtb was problematically too small . . .

The only problem I've ever heard of is toe overlap, which has been described to me as when your toe hits your front wheel during a turn. Potentially very dangerous. You prevent this by either knowing how to handle your bike, or outfitting it with smaller wheels, like 650s. This is why you see a smaller front wheel on small-sized Terrys, for example.

If the bike you're considering is a good fit for you, I don't understand how it could be "too small." If anything, you might consider a different geometry down the road as you learn what kind of cycling you like to do.
