Indicates if the currently matched tag contains the self-closing flag.
Description
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.

* The self-closing flag is the solidus at the _end_ of the tag, not the beginning.

* Example:
*
* <figure />
* ^ this appears one character before the end of the closing ">".
