title: issue with window.open in href attribute
body: <p>I am facing one issue because of URL encoding in window.open function when used under href attribute of link.</p>
  
  <p>Basically I am trying to open a generic popup in my site using window.open function.This popup page accept target page url which will be rendered inside the frame present on popup.aspx </p>
  
  <p>But because of url encoding url parmater which I am passing getting truncated in popup.aspx.cs page.</p>
  
  <p>The same window.open works correctly when directly called from JavaScript function.
  But failing when embedded in Href attribute.</p>
  
  <p>Below is the Code<br>
  Note: input url paramter is a proper decoded url using standard decoding  function. </p>
  
  <pre><code>&lt;a href="javascript:void window.open('Popup.aspx?url=%2FB2B%2FDEV%2FSHARE%2FGRID%2FXML_GRID_PAGE.ASP%3FGRIDTYPE%3D2%26SID%3D33172D0A-565A-43D7-8D50-5C223B6E8C24%26CAID%3D0%26ViewID%3DPATIENTPROFILE%26InstanceID%3D375660844%C3%BF14542276%C3%BF3%C3%BFSTANDARD','','scrollbars=yes,menubar=yes,resizable=yes,left=30,top=30,height=500,width=650')"&gt; link&lt;/a&gt;
  </code></pre>
  
  <p>My assumption is  when window.open embedded inside the href then somehow its get decoded and then passed to target popup page.</p>
  
  <p>Sample url seen in browser.</p>
