Created attachment 12717 [details] IE9 Rendering The sidebar has extra separators displaying in IE9. They are part of the "portal expanded" div and specified under the "class=body" div. Other browsers recognize "background: none !important;" from ext.vector.collapsibleNav.css. IE seems not to see this when the code is minified. However, running with "?debug=true" causes proper rendering. Screen shots courtesy of Krinkle.

Though I can't confirm it right away, I think this is a recent-ish regression. I don't recall this bug from when I last used IE9 on a MediaWiki site with collapsibleNav enabled (from the Vector extension).
Is there any output in a JavaScript console (if IE has something like that)?
Andre, Only this message: "SEC7115: :visited and :link styles can only differ by color. Some styles were not applied to :visited." The console can be found in IE9 by pressing F12 and selecting the Console tab. Try it with "debug=true" to see a number of additional messages, though I'm pretty sure they are unrelated to this particular issue.
Bug 45536 suggests that this happened before and fixed itself magically.

Change 71795 had a related patch set uploaded by Matmarex: Use background-image: none instead of background: none https://gerrit.wikimedia.org/r/71795
Apparently using background-image: none instead of background: none makes it work on IE. Could somebody verify the patch above? (I was relying on a browser screenshot service to debug this.)
Confirmed the above patch with IE9. Thanks!

Well, this should be fixed now, then. The patch will be deployed to Wikimedia wikis according do the roadmap ([[mw:MediaWiki 1.22/Roadmap]]). [Also adjusting product/component.]
