Yes that's correct. That's certainly a problem I sometimes actually observe. Although you could extend it to handle that. But that makes it more platform dependent. E.g. on Linux and MacOS, the scroll events are send to the top-most window under the mouse cursor. It does not matter what window you have focused. I think on Windows it is always send to the focused windows? PRs are welcome. :)
