@cneves I am afraid you cannot change it to ```this.dom_element``` as this is main ```document.createElement('div');``` basically  clicking on ```hide``` ![16px_minus](https://cloud.githubusercontent.com/assets/1065155/2700552/a103d018-c414-11e3-89e9-e6f51010cef6.png) or ```show``` ![16px_plus](https://cloud.githubusercontent.com/assets/1065155/2700554/ad761b9e-c414-11e3-8948-971f42791bcd.png) moves image in main viewport. Any other thoughts how we could fix it?
