inventory widget on iphone view

For some reason when my form is viewed with an iPhone, the inventory widget is cut off not showing all the needed information.  This is not an issue on Android phones.  

I tried to change the CSS based off of what I read on another support question, but it didn't seem to do anything. 

Any thoughts? 

Please try injecting this CSS code:

iframe{
  height: 90px !important;
}
