At some point, some months ago, using a larger font size than the default started preventing you from being able to click item links.
No, it’s not the “interactive” option, it’s properly set to be interactive.
Literally just set the font back to the teeny tiny default, and they’re clickable.
Enlarge the font to be readable, and they’re not.
This is in the default UI and occurs even with all addons removed or disabled.
