jQuery.fn.focus() event shorthand is deprecated

[MattMadgex]

I am upgrading my site to jquery 3 using the jquery migration tool. I get the following error;

jQuery.fn.focus() event shorthand is deprecated

There are 2 instances of .focus() in magnific popup that need updating to be .trigger('focus'). It appears there it no immediate rush as it still works but it seems like it should be updated.

Three years later it's still there.
