In emacs -Q, the `ns-use-proxy-icon' option (introduced in Emacs 27) doesn't appear to have any effect on macOS 12.6.9. See the attached screenshot, and compare it to the one here: https://emacs.stackexchange.com/questions/33680/how-to-remove-the-icon-in-the-titlebar Changing the value to nil also seems to have no effect. While we're at it, the documentation of this could be clearer; neither the manual nor the docstring explain what a "proxy icon" even is. I had to search online, and find the above link, to understand what it is supposed to do. In addition, can this variable be set in a running Emacs? The above Stackoverflow link suggests that you might need to restart Emacs, but AFAICT there is nothing about that in our documentation. Am I missing something about how this is supposed to work?
