Fill doesnt work when curves are of type scattergl

When the type of 2 curves is "scattergl" and there is a fill betweem them, it doesnt work.

Here is a reproducible, minimized codepen: https://codepen.io/GoldBlacky/pen/yyLgOdd

I would also be very happy about a workaround or general direction to try to implement a workaround myself. The reason I need scattergl is because my application is too laggy when using scatter with multiple thousand data points.

Thanks!

从 issue 中链接的最小化 CodePen 复现开始，并将其行为与等效的 scatter 曲线进行比较。跟踪 scattergl 在两条曲线之间填充时的渲染路径，然后验证该复现能够正确渲染填充，同时不会损害使用 scattergl 的性能原因。
