Stormweaver's passive Mind over matter bugged

The Stormweaver's passive Mind over matter is not working when my character's shield gonna and meets element damage. Here is the video link(you can see my status and passive tree under that video):

You can see in the video that starts at 1:55 that I got full mana, and I still died. When I die, the mana is still almost full.

Update:
Alright, I found out the potion caused it,lol

Recoup is not mind over matter. Recoup regenerates a portion of damage (in this case 40%) over 8 seconds. This means that if you take an elemental damage hit of 80 (after all mitigation you have), you will be getting 4 es/second regenerated


Math:

Hit: 80 damage
Recoup percent: 40%
Total recoup: 80 * 0.4 = 32
Recoup time: 8s

Recoup/sec: 32/8 = 4

In fact the video proves that the node is working as intended - your energy shield is recharging while you are actively taking damage, it does not normally work that way.

I mean, the function of the mind over matter is to make all the damage to mana before it comes to life, but in my video, I died before my mana went 0. Does the recharging shield cause it? @0xFourFive#2500

idk if that's what it is, but I haven't had the same issue. I am running similar defensive layers, just on lightning warp instead of spark. I should be taking more damage as a result and I haven't seen it happen.

I realize my answer didn't really address your problem earlier, my apologies.
