Tatiana fight keeps looping the same phase

I keep getting stuck in a loop on the Tatiana fight after she jumps up to a platform and shouts about “rapid expansion of the city”. Tatiana will jump down from her platform, I hit her until she’s vulnerable and throw a key at her. She then teleports back to her platform, repeats her rant about expansion, and the phase starts all over again.

How do I break Tatiana out of this loop?
