Steps to reproduce

1. Use Ibexa Experience 4.6.2.
2. Edit the landing page content type.
3. Go to the ezlandingpage field and open one of the block categories.
4. Try changing the checkbox state of multiple blocks.

It is sufficient to click on the box with the checkbox and the block name to change the checked state (no other click interactions exist for the box and the click area is large).
