public PlaceholderGeneratorInterface::createPlaceholder(array $element)
Turns the given element into a placeholder.
Placeholdering allows us to avoid "poor cacheability contamination": this maps the current render array to one that only has #markup and #attached, and #attached contains a placeholder with this element's prior cacheability metadata. In other words: this placeholder is perfectly cacheable, the placeholder replacement logic effectively cordons off poor cacheability.
Parameters
array $element: The render array to create a placeholder for.
Return value
array Render array with placeholder markup and the attached placeholder replacement metadata.
