Animation cancel spell cooldown and mana consumption bug

I'm specifically using lightning Sorcerer in POE2. When Expanse support gem with +6 second cooldown is on my Orb of Storms, If I cast Orb of storms and during cast time, immediately animation cancel with dodge or cast any other spell, the cooldown will activate, but Orb of Storms will not cast. It will consume mana as well, but not cast the spell.

The same effect is present when I put the Expanse support gem onto Flame Wall. Animation cancelling consumes mana, puts spell on cooldown, but does not cast the spell.

With how chaotic fights are, animation cancelling is neither wanted or intended, but you don't have time to wait until a spell is fully cast before dodging or pressing the button for the next spell to clear swarms of enemies. The Animation cancelling happens unintentionally.

Without Expanse skill gem, animation cancelling still uses up mana and doesn't cast.

I'm not sure if either of these non-casting cooldowns and mana consumptions are intended behaviour, so I'm posting bug report just in case.

Size is important on Orb of Storms, so accidentally cancelling and having to wait a few seconds to actually cast it is probably not what's intended. (Please let me know if I'm wrong)

Bump. Issue still exists.

I think this is actually intended. Using a skill, at the very start, puts the skill on cd. If you cancel afterwards during the animation the spell is still on cd. This happens to me a lot if im not careful on hammer of the gods. Another telling thing is that if I immediately cancel a slam with no animation or attack happening, that button press still consumes an empowered attack granted by a warcry.
