Yup. Annoying, isn't it? It's always been that way, too. I know it's been brought to their attention before and it's so far just been ignored as insignificant. But it doesn't hurt to keep asking them to change it.
Since it isn't technically a bug, but as designed, this might be better stated as an Idea so we can all vote for it.
If it's designed as a 'feature', I seriously wonder whether Adobe engineers ever use their own software...
Adobe, please change this behaviour (and while you're at it, stop Photoshop from grabbing focus every time it's doing something it should be doing in the background; for instance, try 'open as layers in PS' for a few series of images in succession).
