Work done to address https://jira.ez.no/browse/EZP-22260 also included this specific commit, whose goal was to save the user's selection of the "hidden flag" toggle in the Locations window in edit mode:

https://github.com/ezsystems/ezpublish-legacy/commit/c3e8ff555964b165bf4b0872baa9014818086a59

However, that commit caused the following undesired effects:

• "Visible" is the new default in the Locations window, not "Unchanged"
• "Visible" overrides any hide effort of a workflow
• Selecting "Unchanged" as a user and then saving the draft actually saves the selection as "Visible"
