Script src is not loaded when appended with $

[JessicaSachs]

When updating a script node that was previously appended to the DOM with a url, no network request is made.

1. Append script node to document
2. Find script node with selector
3. $node.attr('src', someUrl);

Observe: No network request for someUrl is made in the browser's network tab
See example of jquery handling this: https://jsfiddle.net/w1gg6dgm/

This lack of functionality is manifested in a few different ways...
Appending a script node that already has a src attribute set never requests the file at src.

Example:

const $node = $('<script src=${url}></script>');
$('body').append($node); // should cause the script src to be loaded.... it doesn't
