Our goal is to upload non squared Emoji (more like tiny reaction gifs) so we disabled the enforce square emoji setting. The images are not resized on upload but are still squares when including them in posts because of the CSS rule. Is that the expected behaviour?
When the setting is enabled, the behaviour is exactly the same: the image is not resized on upload but with the CSS.
This is one oddball setting. I am on the fence on even keeping it cause it requires a fair amount of hacking to “make it work” for your definition of work.
