I think you shoud remove the tag emoji you added in front of the tag list:
It looks different on different os:
It may not fit the forum’s design, and it should honor desktop design choices (where there is no icon by default)
If you actually add a tag icon with tag icons component, it will look like this:
So I hid the emoji with CSS, but I think it shouldn’ be here in the first place 
How it is displayed on my forum now:
.md-tlm .discourse-tags::before {
display: none;
}
.md-tlm .tl-replies {
margin-right: 8px;
}
