@kinokatsu,
Sorry for the inconvenience, due to some technical issue it has happened and your post will be restored soon.
We checked with the jsfiddle and observed that pan/reset buttons won’t appear on clicking ‘Scale-Change’ button. Please check this image.
If you are still facing any issue, please reproduce the same in jsfiddle so that we can look into it and help you out.
