Emojis are still causing issues. #2652 claims this issue is fixed, but different combinations of fish_emoji_width (none, 1, 2) seem to affect the behavior without really fixing the problem. In Fish 2.7 I seemed to have avoided the problem with the iTerm workaround, but after updating to Fish 3.0, it started breaking. I can set the emoji width to 1 or 2, but it only works on some emojis (e.g. with 🛠and 🐛, one breaks and the other is ok when setting the value to 1, and the breakage swaps when I change the value). Using a newer emoji (e.g. 🥳) also causes a lot of issues. I have tried as well the ambiguous width values, but it also seems to cause the same random issue.
I installed Fish via brew.
