wp_should_load_separate_core_block_assets(): bool
Checks whether separate styles should be loaded for core blocks on-render.
Contents
Description
When this function returns true, other functions ensure that core blocks only load their assets on-render, and each block loads its own, individual assets. Third-party blocks only load their assets when rendered.
When this function returns false, all core block assets are loaded regardless of whether they are rendered in a page or not, because they are all part of the block-library/style.css file. Assets for third-party blocks are always enqueued regardless of whether they are rendered or not.
This only affects front end and not the block editor screens.
