Description
Given an array of attributes, returns a string in the serialized attributes
format prepared for post content.The serialized result is a JSON-encoded string, with unicode escape sequence
substitution for characters which might otherwise interfere with embedding
the result in an HTML comment.
This function must produce output that remains in sync with the output of
the serializeAttributes JavaScript function in the block editor in order
to ensure consistent operation between PHP and JavaScript.
