Shortcut with 🌐/fn key not showing and/or not working

[fabswt]

When I set a shortcut with the globe/fn key, I don't see the expected symbols in the shortcut definition and, in some cases, the shortcut does not work. For example:

The shortcut works but the display is misleading:

If I set fn-control-leftarrow, it shows up as:

^↖︎

But I would expect it to show up as:

🌐^←

Similar situation with Globe + right, up or down arrow.

The shortcut does not work and the display is misleading:

If I set fn-control-return, it does not work and shows up as:

^⊼

But I would expect it to show up as:

🌐^⏎

FYI, this is with all shortcuts disabled in In System Settings › Keyboard Shortcuts › Windows.
