Alt-tab behaviour issue



I am used to “windows” behaviour of alt-tab - meaning when you release alt-tab you get selected app in focus. With deepin behaviour is that every app gets focus when switching apps - its annoys me because I have say pdf book open, want to alt-tab to something else and then something else gets “on top” of pdf book because during switching it got focus. Can this behaviour be configured somewhere or is it like that by design?
