Why not use a more specific selector instead? If GitHub adds reactions to more places we have to add more exceptions. Is there a comments class that doesn't appear on other pages?

[altrisi]

Another solution for most of those selectors would be to add a class to reaction avatars so they can be referenced directly instead of relying on them being the only span inside the reaction button.

[fregante]

Good idea, we can add a class on the button and then target the contents via span and img

Merging because it’s a fix but hoping for a better fix later. Tagging it as such 👇

I kinda forgot about this PR. IMO it's specific enough because it seems the discussion and release reactions uses the same "newer" markup and I'd expect any (potential) future additional will be the same.

Or perhaps we just implement reaction-avatars on every page (#3978) 😄
