Overheat Support is not working with Fortify Mastery

The new overheat support consumes all of your fortification stacks to increased damage over time by 6-9% per 3 stacks consumed. The Fortify mastery "Recover 100 Life for each fortification lost"

In theory this should give my character 2000 life recovery per second because Im losing/consuming 20 stacks of fortification and then gaining it back on the next hit. However, that is not the case. I am not recovering any life with that mastery, and even just getting 20 stacks and taking damage to drop my life and waiting for the stacks to fall off naturally is not recovering the life.

Other instances of gain X when you lose Y seem to function on "consume" methods like with Kingsguard, you gain 100 life when you lose endurance charges, which triggers off Tectonic Slam or Immortal Call or when monsters "steal" your charges.

I was so excited when I noticed this possible interaction and then completely let down when I also discovered it doesn’t actually work… I assume is has everything to do with the mastery not even working on the most basic level of intention (the recovery happening at natural loss of the fortification buff after its duration has expired).

want an update on whether or not this is intended
