Функция берет содержимое текущего блочного шаблона, обрабатывает в нем шорткоды и блоки через do_blocks(), затем применяет стандартные фильтры форматирования и оборачивает результат в контейнер <div class="wp-site-blocks">...</div>.
Функция помечена как приватная для ядра WP. Ее не стоит использовать в темах и плагинах как часть публичного API, потому что поведение может измениться.

/*
* Most block themes omit the `core/query` and `core/post-template` blocks in their singular content templates.
* While this technically still works since singular content templates are always for only one post, it results in
* the main query loop never being entered which causes bugs in core and the plugin ecosystem.
*
* The workaround below ensures that the loop is started even for those singular templates. The while loop will by
* definition only go through a single iteration, i.e. `do_blocks()` is only called once. Additional safeguard
* checks are included to ensure the main query loop has not been tampered with and really only encompasses a
* single post.
*
* Even if the block template contained a `core/query` and `core/post-template` block referencing the main query
* loop, it would not cause errors since it would use a cloned instance and go through the same loop of a single
* post, within the actual main query loop.
*
* This special logic should be skipped if the current template does not come from the current theme, in which case
* it has been injected by a plugin by hijacking the block template loader mechanism. In that case, entirely custom
* logic may be applied which is unpredictable and therefore safer to omit this special handling on.
