#26630: Plugin Dashicons in admin menu have a glitch in IE

 I'm using a Dashicon icon in a plugin's admin menu entry:
 {{{
 add_menu_page( 'Plugin', $entry_name, $min_access_cap, 'slug', $callback,
 'dashicons-list-view', $position );
 }}}
 Note the `'dashicons-list-view'` as the `$icon_url` parameter, which let's
 the admin menu entry use the List View Dashicon since [26664].

 This works in all browsers, except in IE (tested with IE 11 on different
 computers and different sites), where there's a small "residue" of some
 control character icon on the lower right corner of the actual icon, see
 the attached screenshot.
 When investigating this with the developer tools in IE, this disappears
 once I remove the `dashicons` class from the `div` and leave just the
 `dashicons-list-view` class.
