Which area/package is the issue in?

vitest-angular

Description

I haven't debuged this too deep, but for me it looks like afterEach function from @storybook/addon-a11y/preview is not called with this setup.
Just in case I've checked the minimum setup with clean react + vite and that afterEach is called there and a11y errors are successfully reported both in cli and in storybook ui.

Please provide the exception or error you saw
