/* This text is used to force the code editor's font to be loaded early on if it's a

   In the future, when we allow the user to switch fonts, we'll need to make sure to
   update the font for this text item whenever the user switches. We'll also need to
   wait to initiate a re-measure in CodeMirror until the new font is loaded (if they
