Its my understanding that non-native scrollbar elements (say, Modern
theme) for chrome and content are styled at different times. Thus, the
following userChrome.css override should not affect the content scrollbars:

scrollbarbutton {
  -moz-appearance: none !important;
  background: green !important;
  border: none !important;

Strangely, while it doesn't make the content scrollbarbuttons green, it
doesn't display the button images, either. The same is true for other
scrollbar elements like, thumb, gripper, etc. Even the wormhole element,
scrollcorner, seems to be likewise affected.

Interestingly, this problem doesn't exhibit itself with either the seamonkey 1.6
release or Firebird 0.8 milestone but does in the nightlies of both seamonkey
and Firefox. Also, if the above override is then added to userContent.css, both
the chrom and content scrollbarbuttons display green, as expected.

Reproducible: Always
Steps to Reproduce:
1. Ensure that Modern theme and a recent 1.8 nightly are being used.

2. Create a scrollbar element override within userChrome.css, such as:

scrollbarbutton {
  -moz-appearance: none !important;
  background: green !important;
  border: none !important;

2. Do NOT create a similar override in userContent.css

3. Start browser and display a web page that creates scrollbars (reduce browser
if needed.)

Actual Results:  
The chrome (e.g., on sidebar panel) scrollbarbuttons display as green but the
content page scrollbarbuttons (while not displaying green, don't display the
buttons, either.

Expected Results:  
The chrome scrollbarbuttons should be green and the content scrollbarbuttons
should be the standard Modern theme buttons.
