I think I turned it on the day I reported it. Not sure if it was working before. I noticed something was amiss when I came across 茎, because it shows the Chinese simplified version, where the 又 is replaced with a ス, which threw me for a loop. That made me check what font it was using.
Today, the Yu font is currently active for me, and it has the same issue i.e. With feature off I get the Yu font, with feature on I get the default font. So, it appears to affect multiple fonts.
