Vesuvan shapeshifter and Hooded Hydra cause game to lock up

To recreate have both morphs face down:

Turn Hooded Hydra face up:

The game highlights the Hydra as a target however clicking the Hydra does nothing and the game cannot be progressed past this, clicking the done button just causes the button to disappear. When I found this playing online, at some stage waiting for it, it did update and show that the morph with over 500k P1P1 counters on it, but the game was still froze:
