I did the same find and replace to test this out locally, but you've beat me in creating a PR :-)

I've seen that in the labels overview the labels to have a label icon at the beginning, maybe this has a different css class and fits better?

[jolheiser]

Looks as though Semantic got excited about label images and made their height !important

As much as I hate using !important to fight other !important rules, it seems that until we re-design without Semantic this might be the best choice. I will add another style for these labels for now to correct the emoji size.

Compare these new images with the old ones in the original comment.

Semantic is full of weird hacks like that 😢

Looking at your screenshots, I think the emojis are still a little bit too big and seem not exactly vertically centered in some cases. Maybe you could get them a bit closer to GitHub's styling:

g-emoji {
    font-family: Apple Color Emoji,Segoe UI,Segoe UI Emoji,Segoe UI Symbol;
    font-size: 1.2em;
    font-weight: 400;
    line-height: 20px;
    vertical-align: middle;
}

g-emoji img {
    height: 1em;
    width: 1em;
}

.IssueLabel .g-emoji {
    display: inline-block;
    font-size: 1em;
    line-height: 1;
    position: relative;
    top: -.05em;
}

.IssueLabel--big .g-emoji {
    display: inline-block;
    margin-top: -1px;
}

Hmmm....I'm not sure I agree. This is at 1em and I think it's a tad too small, some of the emoji are getting hard to recognize.
Ultimately I'll go with what most people prefer, but as it stands I think I prefer the images above this one.
The images above are at 1.5em for reference, so there's technically .5em lee-way to work with. 😉

[silverwind]

I like them at 1em, but wouldn't mind a bit bigger, maybe 1.2em. Maybe also match the size of emojis in regular text (I imagine anything bigger than 1em will introduce unwanted whitespace in the line).

[jolheiser]

I think 1.2em looks fine.

Ouch... It was for 1.9.0... sry, already merged :)

[jolheiser]

Ugh, sorry about the Makefile. I've been trying to keep up with that and removing it before committing.
Darn Windows being difficult.
