Usage of deprecated jQuery function

Hi @famethemes!

At first: I really like this Theme and have made dozens of client sites with it (free and pro version). ??

But for the last client I needed some performance optimizations and tried to remove the jQuery Migrate Script. So I turned on script debug:
define( 'SCRIPT_DEBUG', true ); in wp-config.php and looked at the console and Migrate is now logging every failure:

JQMIGRATE: Migrate is installed with logging active, version 1.4.1

Unfortunately and unexpected I saw a next line:
JQMIGRATE: jQuery.fn.load() is deprecated

for this line: /wp-content/themes/onepress/assets/js/theme.js:392:5

The line is showing this: jQuery(window).load(function(){

After googling I saw this usage/load event is deprecated since jQuery 1.8:
https://api.jquery.com/load-event/

It would be great if you can use the preferred method of using this: .on( "load", handler )
Described here: https://jquery.com/upgrade-guide/3.0/#event

Then I can remove the Migrate script and save some KB. ??

Thanks for considering!

All the best,
Torsten
