Divine Ire Cast Speed Bug

Hi!
With the launch of 3.26 Divine Ire changed, and now it has a bug related to cast speed values.
The bug prevents DI from reaching 10 stages and thus reducing the skill's DPS output significantly (and it feels clunky to play).

Few things to note -
1. No repeated clicks or any auto clicker were used in the videos.
2. No weird interactions like a unique item's mod or keystones combinations are effecting this, just cast speed.
3. It looks funny as hell.
