Previously, when saving a custom snippet, the outerHTML of the snippet
was naively read directly and saved as a new custom snippet.
Unfortunately this completely bypasses all cleanup mechanisms that we
have before saving, such as stopping the public widgets, or creating
attachments for cropped or optimized images. This would result in weird
bugs, where public widgets would appear twice when dropping a custom
snippet containing one, as well as the creating a new attachment for any
image that was optimized or cropped before saving the custom snippet
every time it was dropped in the page again.
Unfortunately there is no good mechanism for an option to ask the editor
to clean the DOM without actually saving it, as a temporary measure, the
snippet-save option will instead save the whole page (which will clean
up the DOM) and save the custom snippet after the save, before
refreshing the page and reopening the editor, not unlike some theme
options.
