Steps to reproduce this

There's a mismatch in documentation for visual testing. The current visual tests at main branch only have a simple pixel-to-pixel comparison. I checked dev-2.0 and found the advanced algorithms that are introduced here. However, there was no Gruntfile at the dev-2.0 and it used vitest instead, while the documentation suggested using grunt. The vitest was also headless so I can't manually inspect the visual tests (I used npx vitest to open the tests in a browser but couldn't manually inspect each visual test either)
