[Bug] Parallel axis persisted selection ignores configured areaSelectedStyle

[sgb-io]

Version

5.6.0

Link to Minimal Reproduction

https://echarts.apache.org/examples/en/editor.html?c=parallel-nutrients

Steps to Reproduce

Using the nutrients parallel chart example, apply some brushes to 1 or 2 of the axes. You'll notice that there is a translucent style, but some time later, this gets replaced by a default light blue style. This also overrides any user-provided areaSelectStyle values.

Current Behavior

The user-provided areaSelectStyle is NOT respected

Expected Behavior

The user-provided areaSelectStyle is respected

Environment

- OS: (any)
- Browser: (any)
- Framework: React

Any additional comments?

Suspected solution: when rebuilding persisted parallel-axis covers, preserve and pass the active brushStyle (derived from areaSelectStyle), or have updateCovers inherit controller brushStyle when coverConfig does not specify one, instead of always defaulting to DEFAULT_BRUSH_OPT.

@helgasoft brush one axis, then go and brush a 2nd axis. Notice how the 1st axis brush changes style.

yes, previous axis selections turn gray without opacity, this seems to be by design.
Maybe the API documentation needs to be updated to explain it better. Or change the design to keep the user-defined style.
