When a page tree is moved to another space, some of the links between pages are broken

Environment

1. Create some pages. I.e. following the page tree below:

   Parent page
   ├─ Child page 1
   ├─ Child page 2
   │  └─ Child page 3
   └─ Child page 4

1. Copy the links to all 4 child pages and insert them into the Parent page;

Expected Results

The links should change to point to their new location

Actual Results

In my first test, 2 of 3 links were broken,

in a second test, all of the links were broken:

to

Workaround
