I do not think normal behavior
For example, I'm on a web page, in Apps (Task manager), I have "Microsoft Edge (9)"
And suddenly, I have
Apps : Microsoft Edge (5)
background processes : 4 or 5 separate process in background
If processes were grouped in background processes (as in Apps), why not

There, it's more "borderline" 
Thanks
