This is an illegal drop. There’s virtually no weight being borne by the hands or feet before the knee hits, and the rule requires that “most” of the weight is born on the hands or feet first.
If she didn’t leave the ground, it wouldn’t be an issue, but once she leaves the ground, she has to slow her descent before that knee hits.
Rule 3.9.1: Drops that go directly to the thighs, splits, knees or seat on the performing surface are not permitted unless most of the weight is first borne on the hands or feet or the descent is controlled.
