"Show image" checkbox broken in button Command Editor?

I can't seem to turn off the icons in a menu.
In fact, the menu itself doesn't adhere to the setting either.
It shows the image no matter the state of the "Show image" checkbox :woozy_face:

I was hoping to simply display a checkmark, as described in the docs.
Am I doing something wrong, or is this a bug?

Is the image setting overridden for the whole toolbar, in the Customize window?

Oh, I didn't know that was a thing o.o!
Yes, apparently it was. :sweat_smile:
Thank you!
