Dolphin follow symlink failing example

STEPS TO REPRODUCE
1. Create folder "A" 
2. Create folder "B" in "A"
3. Symlink "B" one level up next to "A"

- A
    - B
- B symlink

4. Open the properties dialog for the symlink and click the "show original" button

OBSERVED RESULT

Nothing happens

EXPECTED RESULT

A new tab/window should open showing the "B" original folder.

SOFTWARE/OS VERSIONS
Operating System: EndeavourOS
KDE Plasma Version: 5.25.5
KDE Frameworks Version: 5.98.0
Qt Version: 5.15.6

ADDITIONAL INFORMATION
If your distribution has e.g. "/bin" or "/lib" symlinked in your root it is easily reproducable on those too.

The "show original" functionality isn't completely broken, I assume the bug appears if the symlinked folder is a child-folder in the current view.
