Changeset 58264 for trunk/tests/phpunit/tests/block-supports/wpCreateBlockStyleVariationInstanceName.php

Block Themes: Add section styling via extended block style variations

Provide users with the ability to style entire sections of a page without
having to tediously reapply the same sets of styles.

This is done by extending block style variations to apply to nested blocks.

See ​https://github.com/WordPress/gutenberg/pull/57908.

Fixes #61312.
