Review Comment:
Just some thoughts:
Do we need to simplify it to only support `richInheritPlainLabel` on the
global model?
(I'm not sure)
+ pros:
+ I guess the most common usage of `richInheritPlainLabel` is when users
upgrade to echarts v6, and find that some text style is broken. They can simply
set `richInheritPlainLabel: false` on the global option to revert it, without
being bothered by debugging. But if they have decided to not to use
`richInheritPlainLabel: false` and fix the broken style one by one, they can
also just modify the text styles directly, but not necessarily set
`richInheritPlainLabel: false` on some specific style option (such as,
`axisLable`, `series[i].label`, ...).
+ If define `richInheritPlainLabel` on the global model, that can be
declared in `types.ts` #`ECUnitOption`. On the contrary, if supporting
`richInheritPlainLabel` every text style, it seems not easy to make a uniform
TS declaration. The `textStyleModel` in this function has been declared as
`Model<any>`, that makes `textStyleModel.get('richInheritPlainLabel')` return
an `any` type, and pass TS check by chance, but not quite correct.
+ cons:
+ `ecModel` is not necessarily exist in this function, tho in most cases
it exists. Is it appropriate to just ignore the cases that `ecModel` does not
exist? I mean `if (ecModel) { ecModel.get('richInheritPlainLabel') } else { /*
just treat it as richInheritPlainLabel: true */ }`.
+ Is it possible that it is hard to fix the style and have to rely on
`richInheritPlainLabel: false`?
But since no ideal approach, it's also fine to use the current
implementation.
