15% damage taken from hits is leeched as life during effect doesn't work with pb overleech

I have petrified blood and I try to use Echoes of creation (which procs both vengeful cry and triggers flasks that have "used when you take a savage hit", so it's definitely a hit).

I have unreserved life above half, which i can clearly see, because my life regen doesn't recover that, so my leech should go constantly, but it doesn't proc at all. I tried to use it with forbidden taste and tainted pact.

it starts working consistently if i put on a soul tether.
