#29474: oEmbed previews ignore width and height attributes
--------------------------+-------------------------

     Type:  defect (bug)  |     Status:  new
 Priority:  normal        |  Milestone:  4.0
Component:  Embeds        |    Version:  trunk
 Severity:  normal        |   Keywords:  needs-patch
  Focuses:                |
--------------------------+-------------------------
 Steps to reproduce:

 Paste the following into the editor:

 `[embed width="200"
 height="200"]https://www.youtube.com/watch?v=n52tAhXzO5E&hd=1[/embed] `

 Note that the preview which appears does not respect the width and height
 attributes of the `[embed]` shortcode.

 This has been narrowed down to a lack of `wp_unslash()` on
 `$_POST['shortcode']` in `wp_ajax_parse_embed()`.
