Emojis in post bodies lack <img> tags and name="" and/or title="" attributes

### Problem I have

Emojis in post bodies appear like regular characters in the page source. For example in the displayed user name they appear with `` tags and `title=""` or `name=""` attributes.

### Solution I'd like

I would be very happy, if the emojis in post bodies would have the same html construct like they do in the row of the usernames, because then it is possible to address them with CSS, which I find super important (e.g. the ability to hide unwanted emojis with client side CSS).
