Bug 53869 [EditorMgmt] Blank outliner when opening/switching to editor
Build 20040303 - multiple windows No exact steps sorry. The problem is that sometimes when opening an editor (ctrl-shift-T) or switching to an existing one will bring it to front, but the outliner doesn't refresh properly. It remains blank. Usually, closing the editor and reopening will make the outline show up after a few attempts.
