Hi !
Here is reproduction steps :
- Create a page Root
- Edit page Root
- Add text with trailing space like this : "Document with trailing space "
- Select the text AND the space
- Click on the icon “link” or CTRL+L shortcut
- Leave everything by default and click OK
- Save and view
- Click in the page A on the link "Document with trailing space "
- Create and Edit
- Add a new text, for example : "Sub document with trailing space " with trailing space, and recreate the link like previously
- The document "Sub document with trailing space " is not visible in the tree.
Hope this will help you.
If needed I can give you acces to my wiki if you want to investigate furthermore.
Best.
