Non-meta gem trigger skills/spells not contributing energy to meta gems

So I believe it was in patch 0.2, they made it such that skills triggered by meta gems do not contribute energy to itself or other meta gems.

However I have noticed that it is very possible that they made it that all trigger skills (including non-meta triggers) do not contribute energy to meta gems.

I wanted to experiment with a low attack damage monk that focused on trigger spells to do damage. Something akin to a melee sorcerer in concept. To that end, I got 'scatter them to the wind' and 'Crackling palm' via thunderfist, together with staggering palm with projectiles powered by nova projectiles and ricochet. Theoretically, with my very fast attack speed, and high crit, it should be comparable to a spark stormweaver and I should be triggering cast on crit extremely frequently.

Initially, I did it with arc and it seemed like it was proccing very infrequently. I switched over to comet knowing that it would be even slower, but the visual could maybe let me know when was there an issue.

In short, when projectiles were flying around critting/killing stuff, there was never any comets falling. I took a video to try and see what was the issue and found out the energy % counter never moved. However, the moment I ashed in with staggering palm and hit a couple of mobs with my my actual melee hit, it started building energy. Even then, the build up of energy seemed awfully slow. I disabled 'scatter them to the wind' and 'crackling palm' and it seemed like my energy build up wasn't any worse.

I am fairly certain this is a bug and not intended as such. It makes an energy build invoker fairly weak and it does have points dedicated to it in the ascendancy tree. I can say with high confidence that staggering palm projectiles are not contributing energy, and with mid confidence that other triggers like scatter/crackling are also not contributing.

Really hope GGG will fix this as this build I feel will be far from overpowered (since most damage modifiers can't contribute to both attack and spells), and I feel that having a melee spellcaster just adds some flavour to the game.

Edit - just realized there is a trigger spell that does work with meta gems, and that is orb of storms triggered bolts. So it may be how individual skills are coded (eg. I have a feeling scattered to the wind doesn't trigger orb of storms either, but it's too messy to tell for certain).

I've done further testing.
The freeze from the explosions on shattering palm does not seem to work to work with cast on elemental ailments either. I recall this not being an issue in season 1 when I used this combo.

So it does seem that all monk trigger effects are not contributing to energy production.
