Sometimes, two dropzones end up at the exact same location (if two
oe_structure are somewhat siblings for example). Before this commit, in
this context, if the user hovered that location with a snippet, then stopped
hovering that location, here is what occured:
- the snippet preview is dropped after the zone 1 and the zone 1 is hidden
- the snippet preview is dropped after the zone 2 and the zone 2 is hidden
- the snippet preview is removed and the zone 2 is shown again
- ... the zone 1 is forever hidden
After this commit, the snippet preview can only be dropped once.
