@TimothyBJacobs, in Gutenberg shim, we used the title key for the schema. Would it make sense to have a direct mapping to the argument here, or is the title key reserved for similar data in schemas?

[TimothyBJacobs]

Yeah it should be title as the prop name. That is how it's defined in the JSON Schema spec.

[Mamaduka]

Thanks for the clarification!

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.

Looks good. The wp-api-generated.js file will need to be rebuilt before committing.

[Mamaduka]

Thanks for the review, @TimothyBJacobs 🙇

The wp-api-generated.js file will need to be rebuilt before committing.

I always forget about it. I wish there was a pre-commit hook for it. To update it, I need to run a full PHP test suite, correct?

Running the following command did the trick - npm run test:php -- --group restapi-jsclient. Though, I'm not sure why it reshuffled the fixture.

[TimothyBJacobs]

Yeah the process is a bit frustrating. Was GB active on your checkout?

[Mamaduka]

Was GB active on your checkout?

No. I've got a separate installation just for core patches.

Edit: I updated fixtures again by running the whole test suite, and it worked.

@Mamaduka Is this good to merge?

[Mamaduka]

@ellatrix, yes, it's good to be merged.

[ellatrix]

Could you merge it?

Should WordPress/gutenberg#61351 be included here or in a separate backport?
