"Load CSS asynchronously" doesn't respect order ($deps)

Have you checked your custom.css $deps first?

I don’t know what you mean by checked my custom css.

This is what I have:

function enqueue_scripts() {
wp_enqueue_style(‘bootstrap’, ‘https://maxcdn.bootstrapcdn.com/bootswatch/3.2.0/flatly/bootstrap.min.css’);
wp_enqueue_style(‘custom’, get_stylesheet_uri(), array(‘bootstrap’));
}
add_action(‘wp_enqueue_scripts’, ‘enqueue_scripts’);

Result:

<link rel=’stylesheet’ id=’bootstrap-css’ href=’https://maxcdn.bootstrapcdn.com/bootswatch/3.2.0/flatly/bootstrap.min.css&#8217; type=’text/css’ media=’all’ />
<link rel=’stylesheet’ id=’custom-css’ href=’https://localhost/wp-content/themes/mytheme/style.css&#8217; type=’text/css’ media=’all’ />

When “Load CSS asynchronously” enabled:

<style type=”text/css” media=”all”></style><style type=”text/css” media=”all”>[my css]</style><link rel=”stylesheet” href=”https://maxcdn.bootstrapcdn.com/bootswatch/3.2.0/flatly/bootstrap.min.css&#8221; type=”text/css” media=”all” />

Can you confirm if using version 2.3 the problem persists?

The problem is still there.

Using “Load CSS asynchronously” my custom script is loaded first. Even when I using $deph wp_enqueue_style('custom', get_stylesheet_uri(), array('bootstrap'));

Thanks to let me know. I will try to reproduce a similar circumstances on my installation to identify the problem.
