Fix <a href="https://core.trac.wordpress.org/ticket/12061" rel="nofollow ugc">known issues</a> when shortcodes are embedded in a block of content that is filtered by wpautop.
<h4>for Theme Developers</h4>
If you are developing a theme to provide this on a marketplace, you better embed the following code in your functions.php. This code filters only the shortcodes you defined. Otherwise you risk a failed review because the code in the plugin filters content in general which may is not acceptet.
<pre><code>function shortcode_empty_paragraph_fix( $content ) {

 // define your shortcodes to filter, '' filters all shortcodes
 $shortcodes = array( 'your_shortcode_1', 'your_shortcode_2' );

 foreach ( $shortcodes as $shortcode ) {

 $array = array (
 '[' . $shortcode => '[' .$shortcode,
 '[/' . $shortcode => '[/' .$shortcode,
 $shortcode . ']' => $shortcode . ']',
 $shortcode . '] ' => $shortcode . ']'
 );

 $content = strtr( $content, $array );
 }

 return $content;
}

add_filter( 'the_content', 'shortcode_empty_paragraph_fix' );
</code></pre>
Another solution that is acceptet at the envato (themeforest) marketplace comes from <a href="https://gist.github.com/bitfade/4555047" title="a Gist on Github" rel="nofollow ugc">bitfade</a>.

The new accessibility javascript in the Appearance > Menus panel in WordPress 3.6 can significantly slow the page load speed when using a large number of menu items (> 50). This plugin defers the accessibility processing to eliminate the scripting bottleneck and allow the Appearance > Menus screen to run much faster and more responsively.

This solution is fairly rough. Hopefully we can develop a robust solution that can eventually become part of the core. Pull requests through GitHub are welcome.
