Fix window controls on macOS
Currently, if I want to use any keyboard shortcuts to control Vivaldi browser window positioning (e.g. If you use an app like Moom) I first have to switch the window to 'Full screen mode' and then back out of 'Full screen mode' in order for the window to be fully controllable.
This makes no sense, it's a bug. I like the UI of Vivaldi over every other browser, I don't want to use the Use Native Window option so this is the crazy process I have to go through for every window I open.
(I know it's not the same, but electron-based apps I have used on macOS have no such impediment, fyi)
