-/**
- * This class is a monkey patch to 'extend' simplehtmldom to recognize <source>
- * tags (HTML5) as self closing tag. This patch should be removed once
- * simplehtmldom was fixed. This seems to be a issue with more tags:
- * https://sourceforge.net/p/simplehtmldom/bugs/83/
- *
- * The tag itself is valid according to Mozilla:
- *
- * The HTML <picture> element serves as a container for zero or more <source>
- * elements and one <img> element to provide versions of an image for different
- * display device scenarios. The browser will consider each of the child <source>
- * elements and select one corresponding to the best match found; if no matches
- * are found among the <source> elements, the file specified by the <img>
- * element's src attribute is selected. The selected image is then presented in
- * the space occupied by the <img> element.
- *
- * -- https://developer.mozilla.org/en-US/docs/Web/HTML/Element/picture
- *
- * Notice: This class uses parts of the original simplehtmldom, adjusted to pass
- * the guidelines of RSS-Bridge (formatting)
