Last week I was resizing a window in High Sierra, and I noticed that the Chrome app in the background was also scrolling. That was completely unexpected. It's long been the case that the window doesn't need to be on top for this behavior, but in this case it wasn't just a focus issue, it was that I was in resize mode. Completely jarring when it happened, but seems related.
