| Steps to reproduce: 1. Open any page in wiki mode
2. Click on Maximize icon
3. Click on on Preview
4. Click on Back to Edit Expected results: Maximize icon and “Exit Full Screen” button are displayed on the screen. Actual results: Maximize icon and “Exit Full Screen” button disappear after Preview → Back to Edit
Also in JS Console the following error is displayed:
