PR #19108 caused some Suspense-related DevTools regressions (more info available on #19368) which we did not catch because of the fact that DevTools tests are only run against the version of React in master.

We should follow the precedent of the regression fixtures tests and have CI run DevTools tests against multiple

The fix described in issue #20179 introduces a regression, especially from an accessibility perspective.

We recently added new Gauge chart(Echarts) to our library, which is great as MVP. Thanks to @krsnik93
Here are some enhancement requests to make the chart more robust. we can either make the improvement in Superset or Echarts.

Request

Current Behavior

The type ErrorMessage doesn't have an id property.

Desired Behavior

It'd be nice id?: string would be added to the type ErrorMessage and set on the outermost component that serves as error message.

Suggested Solution

Add id={this.props.id} to the outer component in ErrorMessage.

While I try to change header titles by passing array of titles to options like below it does not override the headers. Instead it writes new headers first and original data with old headers again from next cell.
