+++ This bug was initially created as a clone of Bug #143837 +++

Description of problem:

in a deviation from old behavior, the windows key cannot be used for
modified keystrokes in the window manager's "preferences -> keyboard
shortcuts" dialog.

I used to successfully set Windows-F1 to switch to workspace 1 (etc)
but it no longer works.  'xmodmap -pm' reports that super_l is <mod4>
and so why is it being treated as a normal keystroke instead of the
modifier that it is?  

Also, I check the bottom radio button in the "preferences -> windows"
dialog (Super is also used as the movement modifier for mouse
actions)...  

This does seem to be a change from relatively recent behavior.

Version-Release number of selected component (if applicable):


Steps to Reproduce:

preferences -> windows -> check super is movement modifier
preferences -> keyboard shortcuts -> move window to workspace 1 ->
Super-F1 

Actual results:

the modified keystroke will not register.

Expected results:

I expect "<mod4>F1" instead of "Super_L" as the keybinding.

Additional info:

xmodmap:  up to 3 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x6d)
mod1        Alt_L (0x40),  Alt_L (0x7d),  Meta_L (0x9c)
mod2        Num_Lock (0x4d)
mod3
mod4        Super_L (0x7f),  Hyper_L (0x80)
mod5        Mode_switch (0x5d),  ISO_Level3_Shift (0x7c)
