When there is enough space, the layout of the children of the date facet pickers do get jumbled up.
To make this space, there's a few ways: 1. Open XWiki on a very large viewport 2. Zoom out 3. Reduce or collapse the width of some columns
In addition, there's also an empty paragraph getting created on every facet picked...
This is likely caused by XWIKI-20931 (or its interaction in a non expected way with the new page layout).
