gnome-terminal: "--name" parameter only works for first window

Question

If I run

1. gnome-terminal --name foo
2. xprop

the window properties are correct:

WM_CLASS(STRING) = "foo", "Gnome-terminal"

If I run this again with anoter name, e.g. gnome-terminal --name bar, xprop gives me for the second window again the same properties

WM_CLASS(STRING) = "foo", "Gnome-terminal"

Expected would be

WM_CLASS(STRING) = "bar", "Gnome-terminal"

Is this behavior intended or is it a bug?

(Background: I need to name the gnome-terminal windows to apply some individual commands in the i3 window manager.)
