assertInstanceof is not required, createElement only returns !Element

Do you suggest to use /** @type {!HTMLElement} */ instead of assertInstanceof()?
I agree with it, since check using instanceof looks redundant in this case.

I changed these assertInstanceof to type cast.
Please let me know if you suggest to change the type of this.domOverlay_ from
HTMLElement to Element.

   this.domOverlay_.className = 'crop-overlay';
   container.appendChild(this.domOverlay_);
 
-  this.shadowTop_ = doc.createElement('div');
+  this.shadowTop_ = assertInstanceof(doc.createElement('div'), HTMLElement);
   this.shadowTop_.className = 'shadow';
   this.domOverlay_.appendChild(this.shadowTop_);
 
-  this.middleBox_ = doc.createElement('div');
+  this.middleBox_ = assertInstanceof(doc.createElement('div'), HTMLElement);
   this.middleBox_.className = 'middle-box';
   this.domOverlay_.appendChild(this.middleBox_);
 
-  this.shadowLeft_ = doc.createElement('div');
+  this.shadowLeft_ = assertInstanceof(doc.createElement('div'), HTMLElement);
   this.shadowLeft_.className = 'shadow';
   this.middleBox_.appendChild(this.shadowLeft_);
 
-  this.cropFrame_ = doc.createElement('div');
+  this.cropFrame_ = assertInstanceof(doc.createElement('div'), HTMLElement);
   this.cropFrame_.className = 'crop-frame';
   this.middleBox_.appendChild(this.cropFrame_);
 
-  this.shadowRight_ = doc.createElement('div');
+  this.shadowRight_ = assertInstanceof(doc.createElement('div'), HTMLElement);
   this.shadowRight_.className = 'shadow';
   this.middleBox_.appendChild(this.shadowRight_);
 
-  this.shadowBottom_ = doc.createElement('div');
+  this.shadowBottom_ = assertInstanceof(doc.createElement('div'), HTMLElement);
   this.shadowBottom_.className = 'shadow';
   this.domOverlay_.appendChild(this.shadowBottom_);
