In 1.26wmf21 we moved gallery styles into a separate resourceloader module. We double load the styles for cached pages. This task tracks ensuring that those styles are removed.

If category pages gets cached, you have to wait 30 days from the last patch.
If not, you can wait 30 days from the first patch, because both patches adding the module to the parser cache, if <gallery> was used.
Special pages not cached, so there is no problem.
1.27.0-wmf.3 seems like a good branch to merge into. 3 weeks is more than enough for most of the category pages to have caught up and the fact that these styles are loaded on pages unnecessarily is more concerning right now.
