nit: this looks like a typo because it's so similar to enabled-text

I suppose

     pxWidth = Math.max(measuringDiv.clientWidth + trashWidth, pxWidth);
     measuringDiv.textContent =
         loadTimeData.getString('extensionSettingsDeveloperMode');
+    measuringDiv.className = '';
     pxWidth = Math.max(measuringDiv.clientWidth, pxWidth);
 
     var style = document.createElement('style');
     style.type = 'text/css';
     style.textContent =
         '.enable-checkbox-text {' +
         '  min-width: ' + (pxWidth - trashWidth) + 'px;' +
         '}' +
         '#dev-toggle span {' +
         '  min-width: ' + pxWidth + 'px;' +
         '}';
     document.querySelector('head').appendChild(style);
   };
 
   // Export
   return {
     ExtensionSettings: ExtensionSettings
   };
 });
 
 window.addEventListener('load', function(e) {
   extensions.ExtensionSettings.getInstance().initialize();
 });
