Expected behavior

When using a let chartInstance: Chart<TType> where TType is a generic such that: TType extends ChartType, accessing chartInstance.config.options?.plugins should cause no problems.

Current behavior

When using a let chartInstance: Chart<TType> where TType is a generic such that: TType extends ChartType, it turns out that accessing chartInstance.config.options?.plugins causes the following error:

Property 'plugins' does not exist on type '_DeepPartialArray<unknown> | (CoreChartOptions<TType> & ElementChartOptions<TType> & PluginChartOptions<TType> & DatasetChartOptions<...> & ScaleChartOptions<...>) | (Function & ... 4 more ... & ScaleChartOptions<...>) | _DeepPartialObject<...>'.
  Property 'plugins' does not exist on type '_DeepPartialArray<unknown>'.(2339)

Optional extra steps/info to reproduce

No response

Possible solution

Most likely, to the ChartOptions interface, some part of the code introduces a DeepPartial<unknown[]> or alike. This results in ChartOptions<ChartType> being a union containing _DeepPartialArray<unknown>, which in turn breaks everything.

The most primitive and functional solution is excluding it manually from the ChartOptions type by wrapping the DeepPartial<...> with Exclude<..., DeepPartial<unknown[]>>.
