Her line was totally wrong heading into the corner. She knew she was going to crash and the obvious skid suggests her rear was fully locked up but she wasn't stopping. She then grabbed a handful of front brake which sent her over the bars.

Spot on.
The rear brake was definitely working as you can see the wheel slide out initially in her attempt to shave speed off to make the angle. Then, as you say, she grabbed the front brake in desperation. There could be one further factor that helped contribute though; releasing the rear brake from the slide. In motor cycle terms known as a 'highside' where the rear wheel loses lateral grip then regains it violently.
Chuck in a dose of heavy front braking and you're going straight to the scene of the accident.
