How to reproduce

• Go to back-office
• filter on sitemap (it is important to arrived on the sitemap without lazy loading)
• double click on the page to open it
• click on a link in the page (it should be an internal link that is not currently displayed in the sitemap due to the filter)

Actual behavior

• An error occured
