LineChart TooltipLine does not display the correct color #822

Describe the bug The Tooltip Line of the LineChart is by default colored as the upper positioned line, this works very unreliably. See image for a visual impression:

The bottom brown vertical line should be red from my understanding.

The indicator lines are drawn by the order of the lines. In your example, brown is the frontest line and that's why you see brown.

An understandable programming pov, but from the design perspective this might need improvement. I understand if this is too much effort to do, so I'd argue, to handle it like syncfusions chart package and to be able to set the line color as one color (if that is not already possible)

I understand it is not good from design perspective. There is an opened issue already. You can follow-up this issue here: #198
