Windows with `macos-titlebar-style = hidden` create new windows when the new tab binding is pressed. This behavior has existed for a long time. However, these windows did not cascade, meaning they'd appear overlapped directly on top of the previous window, which is kind of nasty. This commit changes it so that new windows created via new tab from a hidden titlebar window will cascade.
