Steps to reproduce: a user logs in the back-office, browses the media library to the "Images" folder. Then he switches the sub-items view of this folder in "grid" mode.
Current result: When clicking on a sub-item in grid mode, one is redirected to the preview of this object. Multi-select is consequently impossible.
Expected result: One should be able to multi-select one or more sub-items in order to apply grouped actions.
