+/**
+ * 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)
+ * - 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.
+ * 2. We need to output both render and some extra data, which seems to be imp-
+ *    possible in vue. Current solution is to emit 'parseReady' event when parsing
+ *    is done within render() function.
+ *
+ * Apart from that one small hiccup with emit in render this _should_ be vue3-ready
