Brutus Brain not working in Trial of Sekhema (Bug 3.072.964.684)

I have been playing Trial of Sekhema, and I have pounce with Brutus Brain equipped maily for the predator's mark.
While in normal zones everything is fine, in the trial my minions start taking dmg and die.

In short: Brutus Brain is bugged in "Trial of Sekhema" and does not stop minions from dying.

I have created a /bug report and got number 3.072.964.684.
