I am having an issue with this extension after upgrading MW from 1.22 to 1.26. I have also updated my CategoryTree extension from whatever version I had installed a couple of years ago to the latest available version, so I am not sure to which of these upgrades my issue is related.
In our wiki, back in MW 1.22 and the old CT version, we had changed the color of the category tree bullets by changing MediaWiki:categorytree-collapse-bullet, MediaWiki:categorytree-expand-bullet and MediaWiki:categorytree-empty-bullet to something like this:
This was working fine, but now, in MW 1.26 with the latest CT version, if I click on a ► bullet to expand the category tree, the clicked bullet is replaced by:
... as if the contents of MediaWiki:categorytree-collapse-bullet were enclosed in <nowiki> tags.
Is this intentional behaviour? Or is it a bug?
Either way, how can I change the color (or content) of the bullets in the latest CategoryTree version?
Maybe (just thinking out loud here), editing MediaWiki:Common.css and adding a CategoryTreeToggle style definition there? Haven't tried this...
Thanks in advance
