protected PlaceholderingRenderCache::createPlaceholderAndRemember(array $rendered_elements, array $pre_bubbling_elements)
Create a placeholder for a renderable array and remember in a static cache.
Parameters
array $rendered_elements: A fully rendered renderable array.
array $pre_bubbling_elements: A renderable array corresponding to the state (in particular, the cacheability metadata) of $rendered_elements prior to the beginning of its rendering process, and therefore before any bubbling of child information has taken place. Only the #cache property is used by this function, so the caller may omit all other properties and children from this array.
Return value
array Renderable array with placeholder markup and the attached placeholder replacement metadata.
