Can not affect "r.SetRes" command in editor new window

When playing in "New Editor Window" mode, entering the r.setres command does not change the screen size. This worked in UE4.27, but no longer works in UE5.0.

1. Play in editor with "New Editor Window" mode.
2. Exec "r.SetRes 1920x1080w" command.

Result:

Not affect command and keep window screen size.

Expected:

Affect command and change window size to 1920x1080.
