  * RichContent, The Über-powered component for rendering Post HTML.
  *
  * This takes post HTML and does multiple things to it:
- * - Converts mention links to <MentionLink>-s
- * - Removes mentions from beginning and end (hellthread style only)
+ * - Groups all mentions into <MentionsLine>, this affects all mentions regardles
+ *   of where they are (beginning/middle/end), even single mentions are converted
+ *   to a <MentionsLine> containing single <MentionLink>.
  * - Replaces emoji shortcodes with <StillImage>'d images.
  *
- * Stuff like removing mentions from beginning and end is done so that they could
- * be either replaced by collapsible <MentionsLine>  or moved to separate place.
  * There are two problems with this component's architecture:
  * 1. Parsing HTML and rendering are inseparable. Attempts to separate the two
  *    proven to be a massive overcomplication due to amount of things done here.
