Version 3.46.0 causes Area Chart Gradient to "Glitch" when Hiding / Showing Data Series

[Thimows]

Description

When hiding or showing certain series in an Area chart, the gradient of the series starts to glitch and causes artifacts within the gradient of the series.

Steps to Reproduce

1. Visit this codepen that renders a basic Area chart with 2 series: https://codepen.io/thimows/pen/WNmVyWb
2. Use the legend to hide / show certain series
3. You will notice that hiding/showing series is glitchy and causes artifacts in the gradient of the series.

Expected Behavior

The chart animates smoothly as seen on version 3.45.2 and below

Actual Behavior

The charts renders correctly, but hiding/showing data series is very glitchy and causes artifacts in the gradient of the series

Looking at this now. Just noting, as a clue to what might be going on, that it doesn't appear when the stroke curve is set to straight line.

@rosco54 Thanks so much!

@rosco54 Sorry to bother, but it seems like this is still happening on version 3.48.0 when the data series contains null values as you can see in the updated codepen: https://codepen.io/thimows/pen/WNmVyWb

Is it possible that this edge case is not accounted for?

[rosco54]

I did not specifically consider that edge case. There were plenty of other edge cases that were caught though but I needed to get the main fixes out. This update closed 7 or 8 additional issues as well. I will take a look at this one ASAP.

@junedchhipa @Thimows this issue exists in all revisions since at least 3.40.0, so I'm not treating it as high priority for me, although I will probably not be able to resist pushing further with it. Just don't expect a PR on this one from me.
