It looks like the issue occurs because Hexbear is full-width while default lemmy has padding on the sides. And on current Hexbear the formatting toolbar is right-aligned so it doesn't happen here.
One fix would be to edit line 265 of styles.css where .emoji-picker-container is defined and change transform: translateX(-50%); to transform: translateX(-33%);
Thanks, adding to bug tracker
