Recently on official blog, Microsoft pointed the major difference between the IE on Windows OS and Mobile OS. The lead program manager at Microsoft said that though Internet explorer on both platform has similar features, but on Windows mobile operating system, IE works differently. 
Internet Explorer for Windows Phone operating system excludes support for inline videos. Also, it has been put away from VBscript or Activex support. There is no multi-track HTML5 Audio support, neither use of files access APIs. Drag and drop APIs and ‘open and a new tab’ options are also missing.But also, dragging and dropping on a Phone doesn’t make any sense to me. On the other end, all these features are available in Internet explorer 10 for Windows 8 for PC.
Also, Internet Explorer on Windows phone does not include Window object to load a new window. This is because each Window has its own sandbox in which it is opened.
