How to close a window that's in full screen mode?

[dandavison]

I'm trying to close a vscode window with that's in vscode's "zen" mode and is therefore full-screened (the traditional Mac full screen style, not the newer sort that uses a Desktop).

win:close() is not doing anything. However, if I take the window out of full-screen mode, win:close() works as expected. I've tried the following, but none of them seem to take it out of full screen:

win:setFullScreen(false)
win:minimize()
win:toggleFullScreen()

Can anyone suggest how to do this?
