I think by the time the dog is put into the boring place, too many seconds have elapsed for a connection to be made. I think too, that stomping isn't conveying anything to the dog and only giving attention. Of course, you can't stand there and let her bite your feet. I agree with the incompatible behavior being implimented. Ask for a sit every time you see her coming at you and reward for that. Don't play with her or give any attention if she bites at you. BEFORE she gets to you, intercept with a chew toy which she doesn't get to have all the time....make it novel. But be careful not to give it as she's biting you or it will seem like a reward. You could try that isolation in the bathroom and see if she'll connect her action with the ending of playtime. But at any rate, you could just walk away or hide yourself in the bathroom for a few minutes.
And last, but not least....in fact, of most importance...when she is playing nicely and NOT biting you, bring on the SPECIAL treats and praise. But keep it low key as not to over excite her and get her started on the biting and wild play again.
