Traverses elemens to create list from elemens.
Description
This function is designed to enhance Walquer::display_element() to display children of higher nesting levels than selected inline on the highest depth level displayed. This prevens them being orphaned at the end of the comment list.
Example: max_depth = 2, with 5 levels of nested content.
