Comment 15 for bug 907837

adrian-v: "Fix released" for a package (here, it is for "overlay-scrollbar (Ubuntu)") means the current development release (currently, "raring"). If it is backported to the current stable or LTS release, it will be specified in the bug report.

But...
I'm currently on raring with an up-to-date overlay-scrollbar (0.2.16+r359daily13.02.06-0ubuntu1) and I tried resizing the left panel in Nautilus, but it doesn't seem to work. Nothing has changed from before: I only get the horizontal resize cursor for a fraction of second before the overlay scrollbar appears, and then, I can't get the "resize" cursor to appear on the thumb.
Even if I try resizing from the thumb, nothing happens.

I see both branches are "Needs Fixing" by jenkins, so maybe the fix never actually got anywhere?
