Column visibility settings are not preserved after advance editing and saving a page

Prerequisites

Default state of XWiki (2 side columns)

Steps to reproduce and results

When both columns are hidden using the arrow icon, and a page is edited in Class or Object mode and then saved, both columns become visible again. When editing and saving the same page in Wiki or WYSIWYG mode, only the left column remains visible.

Expected result

The column settings (hidden or visible) should be preserved after editing and saving a page, regardless of the editor mode used.

Note

I recorded a video with steps and results from new XWiki 17.7, but the same can be observed in XWiki 17.4, where this feature was introduced.
