Sanity check:

• Have you checked to ensure there aren't other open Pull Requests for the same update/change?

Code changes

• Are you doing the PR on the next branch?

If the change is a new feature or adding to/changing an existing one:

• Have you created/updated the relevant documentation page(s)?

I mean quotes are not used in the actual HTML source of the specification. Browser developer tools usually display double quotes when inspecting the DOM.
