/access view doesn't always resize containing iframe

If you put a /access/content/... URL into a Web Content tool then when the tool first loads the iframe is resized to the height of the content (tool setting of ???px is only used initially), this makes sense, but then if the user clicks on a folder in the iframe new content is displayed and the iframe isn't resized. If the new content is small it is ok, but if the content is bigger, the user sees scroll bars on the internal iframe.
