| Steps to reproduce:
- On the main page, open the tree navigation dropdown menu by clicking on the arrow right of the "Home" text
- Expand two adjacent sections, like "Sandbox" and "XWiki"
Expected result: The two sections are expanded without any separator between them. Actual result: A separator is displayed between the two expanded (sub-)trees. This can also be experienced by expanding adjacent subtrees:  The separator has been introduced by a style change in XWIKI-22485. |
