MiniMessage - Gradients with > 3 colors render issue

[MiraculixxT]

Today i worked around a bit with some bigger gradients (3 colors or more).
Apparently if there are more then 2 colors and you try to animate them with the offset number it bugs out. For example, first image works correct and second image should be offset half way but it kinda stucks in the middle.

(Images are from the WebUI but behave the same ingame)

For 4 colors it groups to 3 cut of sections and so on...
