[Bug] Rich text in legend does not inherit color from legend configuration if theme specifies `textStyle.color`

Steps to Reproduce

1. Open the codepen
2. Note that the non-rich text in the legend is red (the value specified in legend.textStyle.color).
3. Note that the rich text in the legend is green (the value specified in the theme's textStyle.color).
4. Click an item in the legend.
5. Note that the non-rich text in the legend is blue (the value specified in legend.inactiveColor).
6. Note that the rich text in the legend is green (the value specified in the theme's textStyle.color).
7. Comment out the textStyle.color in the theme and note that the rich and non-rich text match the legend configuration.

Current Behavior

When a chart's theme specifies textStyle.color, rich text within the legend configuration inherits from the theme's text color instead of the colors configured in the legend.

Expected Behavior

I would expect rich text within a legend to inherit from the legend's color configuration (legend.textStyle.color when active and legend.inactiveColor when inactive).

Environment

- OS: macOS Monterey
- Browser: Chrome 108.0.5359.124 
- Framework: the bug is not framework specific, but we are working in React

Any additional comments?

Observations are correct, but an easy fix is to just set bold.color to 'red' instead of relying on inheritance.
Currently legend.textStyle.rich.bold.color inherits first from theme.textStyle.color, then from legend.textStyle.color and inactiveColor.
It should be the other way around.

Guessing the strikethrough means you already inferred this, but clarifying just in case...

If you explicitly set a specific color in the rich text config, it cannot change to match the active/inactive colors set by legend.textStyle.color and legend.inactiveColor because it's hardcoded to a single value.

This issue is labeled with difficulty: easy.
@juliepagano Would you like to debug it by yourself? This is a quicker way to get your problem fixed. Or you may wait for the community to fix.

Please have a look at How to debug ECharts if you'd like to give a try. 🤓

@manishdait have you checked #18260? It seems that this issue was fixed there a moth ago.
