That was becuase not enough information was being passed in for the blocks editing controls to construct the right URL to reload the page. It is also now possible for admin external pages to add some UI next to the turn blocks editing on/off button. For example, when you are editing the list of course catgories, the turn editing off button is now in the right place.
