The following is a userscript I've made to auto-expand text areas when editing comments, using the jquery autoresize plugin:

$(function(){
    $('.note .note_text').autosize();
    $('.new_note .note_text').autosize({
        callback: function(){
            window.scrollTo(0, $(document).height());
        }
    });
    // trigger auto-resize on edit click, not done by default since text has not been changed in the textarea
    $('.js-note-edit').on('click', function(){
        let that = this;
        setTimeout(function(){
            $(that).closest('.note').find('.note_text').trigger('autosize.resize');
        }, 0);
    });
});

I don't use coffeescript so can't do a pull request, but can this functionality be added by default? It improves usability quite a lot IMO.
