Created attachment 14156 [details] Category tree before clicking 1. View any category tree where subcategories are present. Initially, a "CD play" icon (triangle) is used. 2. Click the icon to expand the tree, then click it again to close the tree. 3. Now a "plus" icon is used instead. See the attached before and after pictures (first.png and second.png). This is with MediaWiki 1.22, the latest categorytree snapshot download (wikimedia-mediawiki-extensions-CategoryTree-af0cce6.tar.gz), and Chrome 31.0.1650.63 on Ubuntu 13.10.
Created attachment 14157 [details] Category tree after clicking twice
I just realized this might be a caching problem, as I just upgraded CategoryTree. I cleared my browser cache, and the problem went away -- the "play" icon is now used consistently. If this is still a bug (i.e., CategoryTree code could have prevented the caching issue, say, by appending a unique version number to the image URL), then leave open, otherwise please close.
