A Parser-blocking, cross-origin script is invoked via document.write

On Chrome browsers, a warning occurs:

A Parser-blocking, cross-origin script is invoked via document.write. This may be blocked by the browser if the device has poor network connectivity.

Script in question is:

https://www.google.com/uds/api/visualization/1.0/1195ca6324d5ce101c2f520f3c…mat+en,default+en,ui+en,geochart+en,table+en,orgchart+en,corechart+en.I.js

I’ve tried to correct this by loading the googlejsapi Asynchronously like this in setup.php:

add_filter( 'script_loader_tag', function ( $tag, $handle ) {
    if($handle == 'googlejsapi') {
        return preg_replace("/(><\/[a-zA-Z][^0-9](.*)>)$/", " async$1", $tag);
    } else {
        return $tag;
    }
}, 10, 2);

But this requires a new callback function parm be placed on the script above, for example, in

/google-analytics-dashboard-for-wp/front
/google-analytics-dashboard-for-wp/admin

setup.php

this:

wp_register_script( 'googlejsapi', 'https://www.google.com/jsapi?autoload=%7B%22modules%22%3A%5B%7B%22name%22%3A%22visualization%22%2C%22version%22%3A%221%22%2C%22language%22%3A%22' . $lang . '%22%2C%22packages%22%3A%5B%22corechart%22%2C%20%22table%22%2C%20%22orgchart%22%2C%20%22geochart%22%5D%7D%5D%7D%27', array(), null );

becomes this:

wp_register_script( 'googlejsapi', 'https://www.google.com/jsapi?callback=gadwp_drawFrontWidgetChart&autoload=%7B%22modules%22%3A%5B%7B%22name%22%3A%22visualization%22%2C%22version%22%3A%221%22%2C%22language%22%3A%22' . $lang . '%22%2C%22packages%22%3A%5B%22corechart%22%2C%20%22table%22%2C%20%22orgchart%22%2C%20%22geochart%22%5D%7D%5D%7D%27', array(), null );

But then this requires an additional callback function to work. I’ve tried to target several of the existing functions, but none i tried worked (function not defined errors when loading async).

For cross browser compatibility, perhaps the author can chime in here and recommend a fix or release an update to correct this issue.

Looking forward to a response.
