When moving the cursor between two data points on the same series, there is no fade out animation on the data point. However, if I hover off a series, it does this fade out animation which I would like to deactivate. Looking at the source code, it looks like there is no option to disable this kind of animation. Btw. I set `option.splotOptions.series.animation` and `options.charts.animation` to `false`.
