当itemStyle的color使用回调函数时，线条颜色不能产生相应变化

Steps to Reproduce
When configuring series-line.itemStyle.color as the callback function, only the inflection point changes color, and lineStyle does not take the value according to itemStyle.color as stated in the document.
This problem was raised and fixed in 2019. Now the problem reappears in the new version and is not solved.
Current Behavior
When the color of itemStyle uses the callback function, the line color cannot change accordingly.
Expected Behavior
When the color of itemStyle uses the callback function, the line color can also change accordingly.

This does not appear to be a bug, in my opinion. When itemStyle.color is defined as a callback function, it has the capability to return different colors based on varying data indices. However, lineStyle.color does not support using different colors for different data indices. As a result, when it is specified as a callback, it defaults to the series color as a graceful fallback.
This behavior does not match the document description, and the returned value belongs to a reasonable color range. It is unreasonable to assume that it is not a bug simply because it is returned using a callback function. Especially when the document explicitly states that lineStyle can inherit from itemStyle, this detail is illogical and independent of whether itemStyle uses callback function methods.
if it's no a bug, how to choose when I need to modify the color of a segment of a line based on different numerical values, but it is not a gradient scene？ @Ovilia
Currently, ECharts doesn't have the ability to set line styles of different segments, if visualMap doesn't count.
Perhaps adding support for callback function types to lineStyle would be more in line with the documentation's explanatory logic.
@Ovilia When there are multiple series, visualMap cannot support the simultaneous use of multiple configurations, and conflicts will be automatically merged.
#17138 Maybe you can follow this feature. This is an epic feature so it's still in pending state and I don't know if when I have time to do this.
ok, i know that
