[mattamon]

Steps to reproduce:

Drag & Drop e.g. Shop to the bottom of the tree so the x icons appears. Drag it very slowly over the upload folder.
Sometimes the symbols overlap.

Another way:
Go to the documents tree, move the de tree under the print folder.
Then grab the de tree again and pull it to the bottom as seen in the image.

Actual behaviour
Icons are overlapping

Expected behaviour
Icons are not overlapping
