Before this commit, the preview of the dragged snippet didn't work when moving a dragged snippet from a drop zone to an other drop zone when there was no space between those drop zones. It is because, in this case, the over event of the second drop zone is triggered before the out event of the first drop zone. task-2312878 closes odoo/odoo#66267 X-original-commit: 66b468626e046a13a463cff3a2285801016f3ed7 Signed-off-by: Quentin Smetz (qsm) <qsm@odoo.com>
