[Bug]: @storybook/experimental-addon-test removed testing-library props from canvas

[rhuanbarreto]

Describe the bug

When trying to integrate the @storybook/experimental-addon-test plugin, everything worked "fine" but of course I had some quirks. Many on reproducibility between the addon and on the browser but all of them were actual issues on my code. Only one thing is bugging me: tsc.

Typescript now complains that the type of the canvas property of the play function context doesn't have the functions from testing-library anymore. Before, on @storybook/addon-interactions I had all those testing library functions under canvas and I didn't need to use within(canvasElement).findBy...()

Error:

error TS2339: Property 'getByTestId' does not exist on type 'Canvas'

Reproduction steps

Very hard to reproduce as this is coming as a regression on my storybook. Those are my addons:

addons: [
    getAbsolutePath("@storybook/addon-essentials"),
    getAbsolutePath("@storybook/addon-designs"),
    getAbsolutePath("@storybook/addon-themes"),
    getAbsolutePath("@chromatic-com/storybook"),
    getAbsolutePath("@storybook/experimental-addon-test"),
    getAbsolutePath("@storybook/addon-a11y"),
  ],
