Positioning of Windows, among other window system interactions, is
inherently platform specific. We added language, primarily in support of
Wayland, to clarify this, but I can easily imagine other windowing
environments where this is also true. We should try for consistency
where possible, but recognize that some things are under control of the
system.

I'm forwarding here since it's unrelated to the specific issue.
The existing behavior on Linux is to center the windows. I think we
should let the window manager decide and don't touch the initial
position (unless the user sets it).
On mutter, for example, there's an option to automatically center the
windows. There's also an option to automatically maximize windows near
screen size (and we probably break it).
There's also window managers like i3 on which making effort to center
the windows are pointless since it's a tiling wm.
We should let some platform details be different, I think.

Question. I see different behavior between macOS and linux mint with
the attached program (unmodified master branch).
On mac, the alert window is always positioned at the upper left
corner, while on linux it is correctly placed at the center of the
screen. Is this expected?
Also on mac, as I understand it, there is no "maximized" state, only
full screen. So when the alert window comes up, the main window slides
out of view and all we see is the black screen and alert widow at the
upper left corner.
Unless we move the main window to another monitor. In that case I can
see a number of differences:
1. main window in normal state, the alert comes up on a primary
screen and not on the screen where the main window is located
2. when main window is "maximized" to full screen, both screens go
into full screen mode, one (secondary) with the main window, the
other (primary) with a black background. an alert pops up on the
primary screen (i.e. other than the screen with the main window),
but this time it is correctly positioned at the center of the
primary screen.
I feel this behavior (on mac) is unexpected. Any ideas?
