Script dependencies generates totally different outputs

The block of code beneath is meant to generate an inventory of dependencies for a given deal with e.g. jquery.

perform get_deps() {
    international $wp_scripts;
    $wp_scripts->all_deps( 'jquery' );
    $output = [];    // Initialize an empty array
    foreach( $wp_scripts->to_do as $deal with ) {
        $dep = wp_scripts()->registered[ $handle ];
        $output [] = $dep->src;
    }
    $end result = $output;
    return $end result;
}

The perform beneath is a fast take a look at of the get_deps perform to examine if it spits out the anticipated listing of dependencies.

perform display_scripts() {
    print_r( get_deps() ) ;
}
add_action( 'wp_enqueue_scripts', 'display_scripts',  PHP_INT_MAX );

This works as anticipated nevertheless if print_r( get_deps() ) ; is named with the script_loader_tag filter, it produces a sudden listing.

As a fast take a look at, if I change jquery with lazysizes which has no dependencies like so:

perform get_deps() {
    international $wp_scripts;
    $wp_scripts->all_deps( 'lazysizes' );
    $output = [];    // Initialize an empty array
    foreach( $wp_scripts->to_do as $deal with ) {
        $dep = wp_scripts()->registered[ $handle ];
        $output [] = $dep->src;
    }
    $end result = $output;
    return $end result;
}

And shortly validate it with:

perform display_scripts() {
    print_r( get_deps() ) ;
}
add_action( 'wp_enqueue_scripts', 'display_scripts',  PHP_INT_MAX );

The output is: Array ( ). Up to now so good. Now if print_r( get_deps() ) ; included in a block of code with the script_loader_tag filter, the outcomes are fully totally different. Here is the take a look at:

perform take a look at() {
    print_r( get_deps() ) ;
}
add_filter( 'script_loader_tag', 'take a look at', 10 );

which produces:

Array
(
    [0] => /wp-includes/js/jquery/jquery.min.js
    [1] => /wp-includes/js/jquery/jquery-migrate.min.js
    [2] => 
    [3] => https://area.com/wp-content/themes/theme-name/js/plugins.js
    [4] => https://area.com/wp-content/themes/theme-name/js/script.js
)
Array
(
    [0] => /wp-includes/js/jquery/jquery-migrate.min.js
    [1] => 
    [2] => https://area.com/wp-content/themes/theme-name/js/plugins.js
    [3] => https://area.com/wp-content/themes/theme-name/js/script.js
)

I’ve no thought why it does this because it ought to be Array(). What am I doing fallacious or overlooking?
