Thank you, @fai-sal!

The correct directory for Playwright e2e tests is test/e2e/specs/editor/various.

I also would recommend checking the project e2e test best practices documentation - https://developer.wordpress.org/block-editor/contributors/code/testing-overview/e2e/#best-practices.

Appreciate all your hard work here 🙇

The e2e tests will need to be rewritten to utilise Playwright APIs such as getByRole.

A lot of the await will be able to be removed as well. You should find it's a lot easier to author the tests as well.

Thanks for migrating to Playwright. A few comments about the test selectors 🙏

Hi @getdave, If you can allocate some time, can you please review the PR again. Thanks 🙇

I think we should look to land this in time for WP 6.5. I've put it on the board for that project which should ensure a number of 👀 on it.

Left a few nits but this looks good to me.
