workspace, previous doesn't work after movetoworkspace, 2

[c02y]

I got

bind = $mainMod SHIFT, 2, movetoworkspace, 2
bind = $mainMod, X, workspace, previous

So when I open a new window in a workspace such as workspace 1, after I use the binding Super+Shift+2 to move the window into another workspace like 2, then I try to use Super+x to switch back to the old workspace 1, it does nothing.

When I use bind = $mainMod, 2, workspace, 2 to switch to workspace 2 and Super+x to switch back to workspace 1, then do the above instruction, Super+x still can not switch back to workspace 1, it seems movetoworkspace dispatcher clean the workspace-previous stats.

Not sure if this is a bug or not.
