hide_window_decorations titlebar_only breaks when entering fullscreen (macos)

[Spo0on]

Describe the bug
The hide_window_decorations titlebar-only works well when in non-fullscreen mode: the native titlebar and window controls on native titlebar disappears, the corners are round. But once i enter in fullscreen mode and then back to window mode the window controls of native titlebar reappear. That's annoying because they cover the actual content of window

To Reproduce
Steps to reproduce the behavior:

1. Set the hide_window_decorations to titlebar_only
2. Open a terminal window
3. Enter native fullscreen mode (cmd+ctrl - f)
4. Exit native fullscreen mode
5. See error (native window controls on top left corner)
