Frame advancement doesnt reflect in the slider!

[ThatChair]

In v1.1.0 (which hasn't been released as of this post), when advancing or going back a frame, the slider doesn't move at all!

For some reason, this code should cover it, but it doesnt...

animPercent.addListener { _, _, newValue ->
if (isAnimationPlaying.get()) {
sliderPointPos.set((newValue.toDouble() * ((sliderLine.endX - sliderLine.startX))) + sliderLine.startX)
}
}
