Cast on Shock +1 corruption energy gain

I have 38% increased energy gain on tree.
My level 19+1 20% cast on shock has 54%+3%+15%=72% increased energy gain.
I use impetus support for 40% increased energy gain.
That should sum to 38%+72%+40%=150% increased energy gain.

However, when I click the right arrow to expand the skill tooltip, it lists 147% increased energy gain.

When I swap to an uncorrupted level 19 cast on shock, it's still 147%, so I think the energy gain just isn't accounting for the +1 gem level corruption.

I tested against the quadrilla boss in cruel act 3 and got less than 100 energy every time I shocked it (2*20*2.5), so it's not just a visual thing; the gem is not producing the correct amount of energy.

Same here, with Barrier Invocation. Bug report reference number 830 812 603.

With a non-corrupted level 19 Barrier Invocation, I have the same energy gain as with a corrupted level 20 (19 + 1 from corrupted).

It seems like the energy gained does *not* take into consideration levels from corruption.
