Comment:

 I just noticed that this issue still exists, but with elements with
 z-index greater than '''100'''.
 I can see that now the #adminmenuwrap element z-index is set to '''99'''
 (wp-admin/css/wp-admin.css:
 [http://core.trac.wordpress.org/browser/trunk/src/wp-admin/css/wp-
 admin.css#L1923]):

 {{{
 .sticky-menu #adminmenuwrap {
         position: fixed;
         z-index: 99; /* Match the z-index of .wp-submenu to ensure flyout
 menus don't appear underneath main column elements */
 }
 }}}

 and '''99''' is the z-index applied to the .wp-submenu element, instead of
 the '''9999''' set on the element here:
 [http://core.trac.wordpress.org/browser/trunk/src/wp-admin/css/wp-
 admin.css#L1762]

 {{{
 #adminmenu .wp-submenu,
 .folded #adminmenu a.wp-has-current-submenu:focus + .wp-submenu,
 .folded #adminmenu .wp-has-current-submenu .wp-submenu {
      padding: 7px 0 8px;
      z-index: 9999;
 }
 }}}

 So, any element inserted into the content with z-index of 100 or greater
 will be displayed over the submenu element.
