bug#64347: 30.0.50; Some customize faces shown as edited with -Q

[Stephen Berman]

0. emacs -Q
1. M-x customize-face RET RET
2. Toggle all face entries in the buffer *Customize Faces* (e.g. by
   creating this keyboard macro: C-s C-q C-j S RET C-f and then
   executing it 164 times) and search for the string "EDITED" in the
   buffer.
   => The following faces show the State "EDITED, shown value does not
   take effect until you set or save it.":
   confusingly-reordered
   custom-button
   custom-button-mouse
   custom-button-pressed
   mode-line
   mode-line-highlight
   mode-line-inactive
   tab-bar-tab
   tool-bar
   All other faces show the State "STANDARD".
3. Clicking the State button of these faces and selecting either "Undo
   Edits" or "Revert This Session's Customization" does not change the
   State shown.
4. Clicking the State button of, e.g., mode-line and selecting "Set for
   Current Session" changes the State shown to "SET for current session
   only."  I see no difference in the appearance of the mode line before
   and after this State change.
5. Clicking the State button of mode-line again and selecting "Revert
   This Session's Customization" changes the State shown back to
   "EDITED, shown value does not take effect until you set or save it.",
   and again the appearance of the mode-line is unchanged.
