Test using WordPress Playground

The changes in this pull request can previewed and tested using a WordPress Playground instance.

WordPress Playground is an experimental project that creates a full WordPress instance entirely within the browser.

Some things to be aware of

• The Plugin and Theme Directories cannot be accessed within Playground.
• All changes will be lost when closing a tab with a Playground instance.
• All changes will be lost when refreshing the page.
• A fresh instance is created each time the link below is clicked.
• Every time this pull request is updated, a new ZIP file containing all changes is created. If changes are not reflected in the Playground instance,
  it's possible that the most recent build failed, or has not completed. Check the list of workflow runs to be sure.

For more details about these limitations and more, check out the Limitations page in the WordPress Playground documentation.

The tests are failing but that is expected. I'll fix them in a couple of hours (need to go now).

Thanks @anton-vlasenko! This looks right to me.

Could we add a unit test that specifically covers a HEAD request with ?_fields present?

Awesome! I'll add them today and let you know once they're ready.

@TimothyBJacobs I've added more tests in 0b08957. This took longer than I anticipated, but I've double checked they cover the regression.

Sweet. Thank you!

Thanks for working on this, @anton-vlasenko!

@TimothyBJacobs, do you have time to commit this before Beta 2?
