On beta labs and ee-flow, the Expand|Collapse|Small view icons, the action menu [...] ellipsis, and the icons for Permalink, Hide, etc. in the action menu are all blank. This also affects the Compact Personal Bar beta feature on beta labs, the items in its drop-down such as Notifications have no icon. ErikB figured out it's a regression in background-image-svg handling introduced by the change to mediawiki.less in gerrit I39ea2004b.
Change 129023 had a related patch set uploaded by Spage: Resolve complex arguments to LESS helper functions https://gerrit.wikimedia.org/r/129023
Merged and backported to 1.23.
