Before, this was only enforced on the Windows platform, where multiple calls would result in errors. But logically it is the correct behavior, and it allows simplifying the code as well.
This also includes a minor change to correctly use
platform.system() == "Windows"
rather than.startswith("Windows")
.Note that this requires the fix in PR GH-28328 to work properly on Linux.
Also, note that this has no effect on the position of the completion window while scrolling the editor window, which isn't updated anyways as far as I can tell.
