Looks good

This looks good, just noticed in Editor.jsx:

this._cm.on('keyup', () => {
      const temp = `line ${parseInt((this._cm.getCursor().line) + 1, 10)}`;
      document.getElementById('current-line').innerHTML = temp;
    });

This inserts "line 6" into the DOM for screenreaders to discover, so this should also be translated. If you'd like to do this in another PR, then can you open an issue so we don't forget.
