The patch looks good here. The only thing is I get this printed to the
console:

2024-11-20 21:11:36.609 emacs[18867:241457] ERROR: Can't have a toolbar in a window with <NSNextStepFrame: 0x7f8db350c7e0> as it's borderview

I don't think I've ever seen NextStep explicitly mentioned in macOS
code before, other than the "NS" prefix.

I'm going to hazard a guess that the first if at the top of
createToolbar needs another test for when we're in non-native
fullscreen or something.

Native fullscreen displays the toolbar, non-native doesn't because it
uses the borderless stylemask. Perhaps a check on the stylemask would
be enough to cover both this and undecorated.
