Only for the currently focused window which is inexplicably weird

A lot of the cursor weirdness on macOS comes from the window server owning the cursor and only passing events to active windows.

It's kind of nice, though, because you can click anywhere on a window to focus it. If you want to interact with a background window without focusing it, hold Cmd and click.

On every app but the System Settings app since it is so busted it takes 5 or 6 clicks before it focuses.
