[Bug]: Type of canvasElement from getStoryContext is unknown

[unional]

Describe the bug

import { getStoryContext } from "@storybook/test-runner"

// in postVisit
const storyContext = await getStoryContext(page, context)
storyContext.canvasElement // type unknown should be HTMLElement

This is caused by:

interfact StoryContext<TRenderer extends Renderer = Renderer, ...> ... {

  canvasElement: TRenderer['canvasElement']
}

type Renderer = {
  canvasElement: unknown
}

Note that in both preVisit and postVisit the value of canvasElement is undefined at runtime.
Not sure if that is intentional or it's a bug. In either way the type and runtime doesn't match.
