add_theme_support function doesn't add some features it says in comments

[superpoincare]

The lines ​https://github.com/WordPress/WordPress/blob/master/wp-includes/theme.php#L2321-L2330

say that in 5.0.0 some features were adding to the function add_theme_feature:

"... 'editor-styles', and 'wp-block-styles' features were added."

However the function below doesn't add them.

[joyously]

There was no code change needed to add those new features, so only a comment was added to document the names.

Hi @superpoincare,

Thanks for the ticket! Can you post code that shows this is not working as expected? The ​last line of the function adds theme support for the specified feature. The switch() statement only handles more complex features that have additional arguments passed.

Oh my misunderstanding then.

Trying to figure this previous ticket I raised, reached me to that wrong conclusion: https://core.trac.wordpress.org/ticket/45551

That ticket is valid though: child theme doesn't load parent editor-style.css in the new editor.
