- Activate mission control
- Chose app - eg. Click Safari
- Mission control exit animation plays, but an app OTHER than Safari has focus.
I cannot express how frustrating this is. There is another (possibly related) issue also occuring: if I have an app eg. Chrome on a full-screen space, selecting that space will focus it, but another Chrome window from my desktop will then appear in focus, on top of the full-screen Chrome space.
Might help for context: macOS Sierra lost focus Finder when using mission controls
