Keyboard isn't showing when I open quick switcher after first app start

Hi! I set in mobile settings “Quick Switcher” as quick action.

But I noted, that when app starts at first and open quick switched the keyboard isn’t showing, I have to tape on input block for this.

When I open quick switcher at 2nd time it works fine: keyboard is showing automatically

It looks like a bug ? thinking
