/**
 * Indicates if the currently matched tag contains the self-closing flag.
 *
 * No HTML elements ought to have the self-closing flag and for those, the self-closing
 * flag will be ignored. For void elements this is benign because they "self close"
 * automatically. For non-void HTML elements though problems will appear if someone
 * intends to use a self-closing element in place of that element with an empty body.
 * For HTML foreign elements and custom elements the self-closing flag determines if
 * they self-close or not.
 *
 * This function does not determine if a tag is self-closing,
 * but only if the self-closing flag is present in the syntax.
 *
 * @since 6.3.0
 *
 * @return bool Whether the currently matched tag contains the self-closing flag.
