Guatelitzi's Abletion support not giving power charges properly

The lineage support gem Guatelitzi's Abletion states that "Offerings from supported skills grant you a power charge every 4 seconds". However, the support only gives the first charge and stops granting additional charges even when the offering is still active.

My current offering skill has a duration of 10.47 seconds, so in theory it should grant power charges twice during the effect, but I only get 1.

I have a duration of 16 seconds and it only gives 1, can confirm not working as worded.

Here to confirm with 13+ seconds duration, you only receive 1 power charge after the first 4 seconds.

Found this thread after trying to create little Power Charge engine for my Bonestorm Witch and... Yeah. I was so happy after first 4 seconds after I found this interaction and then sad after the 8th second.

GGG pls next patch
