 When dragging a metabox over an active TinyMCE instance in a post/page
 edit screen, the metabox can get "stuck" (i.e., it stopping moving with
 the mouse). This only happens with TinyMCE and not the "Text" textarea.

 '''To reproduce:'''

 1. Uninstall plugins
 1. Install a default theme (I used Twenty Thirteen)
 1. Go to ''Pages > Add New''
 1. If it is not activated already, click the "Visual" tab to activate the
 TinyMCE instance
 1. Grab the featured image metabox to activate the sortable (i.e., drag
 and drop) functionality
 1. Move the box over the TinyMCE area
 1. Continual movement over the area will cause it to get stuck

 The following screen grab shows how the cursor separates from the metabox
 as it gets stuck:

 It's kinda hard to understand it with that image, so here's a movie that
 shows the issue:

 I have tested this in Safari, Firefox, and Chrome on OS X. All browsers
 produce the same issue. The issue persists with MP6 as well.
