Blahaj Lemmy Meta

hi, I suspect if I did some searching I could find my answer (so apologies up front for being lazy and not doing enough research up-front 🙊) but I have noticed every time I type : and then start typing the name of an emoji, for example :sob: (i.e. 😭), there is a list of emojis that start to match what I'm typing:

The emojis rarely match the auto-complete I'm expecting (which is based on doing this in other contexts like Slack with standard unicode emojis), and often there are custom emojis in addition to the standard ones that if I accidentally tab and hit enter to accept, results in an embedded image.

Incidentally, my fingers somewhat automatically start to type emojis like :sob: and this auto-complete feature is essentially "broken" for me by the large number of custom image emojis (notice the emoji I'm looking to autocomplete when I type :sob isn't showing up in the top part of the list).

Admittedly this breaks my flow, but I'm not complaining as much as wondering what this custom image emoji feature is, whether it's a Lemmy thing or an instance specific thing, and how much other people use it (do other users like these custom emojis, and their easy / automatic finger flow is accustomed to these options)?

The custom emojis are cute, tho 😄
