+
+The \Verb'\standaloneenv' command patches an environment in a way that the
+environment produces a separate page. This can cause issues with environments that
+are also patched by TeX4ht, for example tikzpicture. This happens with the 
+tikz class option for Stadnalone. The result is that TikZ pictures are not 
+converted to images correctly.
+
+I think we can just disable this command.
