Steps to reproduce the bug:
- Add a "Text-Image" snippet on the website page.
- Take an "Inner content" snippet from the right panel and drag it from
a dropzone to another. It has to be fast so that the order of the "over"
and "out" dropzone events is "over" > "over" > "out" and not "over" >
"out" > "over" as usual.
-> The exited dropzone is not correctly displayed.
The problem is that since [1], the website is inside of an iframe. Due
to that, the snippets menu does not have a direct access to the
dropzones. To solve the problem, the already defined `$dropZones`
variable is used instead of searching the dropzones inside the DOM. For
the snippet editor, the problematic line has been deleted at it is
already handled by `_outPreviousDropzone()`. This is acceptable since
the commit that introduced `_outPreviousDropzone()` ([2]) and the commit
that introduced the removed line ([3]) were both introduced to handle
the case of an "over" after an "over". In other words, as
`self.droppped` will always be `true` when
`self.dragState.currentDropzoneEl` is set and it will always be `false`
when `self.dragState.currentDropzoneEl` is not set, the problematic line
can be removed as it is already handled in `outPreviousDropzone()`.
