It's a result of the way tabbed windows are implemented. Although it appears
that only one window is visible when you have several tabbed, as far as the
part of the OS that controls them is concerned, they're all normal visible
windows -- it's only at the screen drawing end of things that drawing is
omitted for all but the active one. Because the visible property is part of the
former machinery, it's now largely useless.
The issue of windows hanging around for a very long time is possibly a bug, but
they can legitimately hang around, even if unseen. Windows can be closed, but
they can also be ordered out, which means they don't appear on screen but still
exist.
Much of this was introduced with window tabbing in 10.12, and although it might
sound a bit odd, the result is that tabbed windows are much snappier for users.
The problem is that the scripting parts of things -- the -orderedWindows method
of NSApplication, and the visible property of windows -- haven't been adjusted
accordingly. So apps that rely on the built-in stuff produce the sort of thing
you see.
In many cases the people who build the apps probably aren't aware of the
problem. And if they are, they can't fully fix them because it's stuff beyond
their control -- they have to work around them.
