title: DropDownStyle set to DropDownList looks disabled but isn't?
body: <p>It seems that the Windows 10 style of Combobox looks disabled when I change it's <code>DropDownStyle</code> to <code>DropDownList</code>.</p>

  <p>On the left is the Combobox before any user interaction. On the right is when a user clicks on it to open it.</p>
  
  <p>Now, I don't like changing default design to something the user might not expect but to me the default design makes it look disabled and might confuse the user.</p>
  
  <p>I've tried setting the control's <code>BackColor</code> to white but there was no change.</p>
  
  <p>I want the behavior of <code>DropDownList</code> where the user can only pick from the options available and not write in a new option but the look of <code>DropDown</code> (a plain white background).</p>
