Custom COPYINFOTIP Hotkey Not Working

I followed the manual to create a button with the command Clipboard COPYINFOTIP, then assigned a custom hotkey to that button.

I hovered over a JPG, the infotip appeared, but pressing the custom hotkey does nothing except making the infotip disappear. It doesn't copy the text to the clipboard.

The default hardcoded shortcut Ctrl+Shift+Alt+C works fine (and the info tip does not disappear).

Is this a bug?

Also, the default shortcut doesn't appear in Customize > Keys, which matches the manual saying it's available by default without needing to create a hotkey for it.
If possible, would you consider making this shortcut not hardcoded? (Of course, this isn't a big deal, since other hotkeys can override it anyway. I just think it's not ideal that it doesn't show up in the list.)

What key did you try to use?

I tried Ctrl+Alt+Shift+J and Ctrl+Alt+Shift+T (I was just testing this feature without actually planning to remap it to something else, so I only tested these two).
That reminds me — after seeing your reply, I also tried some simpler hotkeys, and they worked fine.

Thanks, this will be fixed in the 13.23.1 beta.
