+ * doing so leaves behind another entity, e.g. &amp;gt; if decoded would
+ * create &gt; which is another entity itself. This seems to escape the
+ * usual behaviour where any two paired entities creating a HTML tag are
+ * usually decoded, i.e. a lone &gt; is not decoded, but &lt;foo&gt; would
+ * be decoded to <foo> since it creates a full tag.
+ *
+ * Note: This function is poorly explained in the manual - which is really
+ * bad given its potential for misuse on user input already escaped elsewhere.
+ * Stackoverflow is littered with advice to use this function in the precise
+ * way that would lead to user input being capable of injecting arbitrary HTML.
