'Can't find instance of 'jQuery.expr[":"]' while upgrading to jQuery 3.x

I'm in the process of upgrading from jQuery 1.11.2 to jQuery 3.1.1, using the jQuery-Migrate plugin version 3.0.0.

On every page load, I get this warning:

JQMIGRATE: jQuery.expr[":"] is now jQuery.expr.pseudos

The problem is that I can't find the offending code, or any variation of it, in either my code or 3rd party libraries. I did find this example, but I don't think it's the same?

$.fn.visible = function() {
  return this.css('visibility', 'visible');
};

$.fn.invisible = function() {
  return this.css('visibility', 'hidden');
};

Update 1: Here's the JS code loaded in a web page:

<!DOCTYPE html>
<html>
<head>
  <title>UpgradeJquery</title>
  <script src="/assets/jquery/jquery.min.js?body=1"></script>
  <script src="/assets/jquery-migrate/jquery-migrate.js?body=1"></script>
  <script src="/assets/jquery-ui/jquery-ui.min.js?body=1"></script>
  <script src="/assets/application.js?body=1"></script>
</head>
<body>
  <h1>Home#index</h1>
</body>
</html>

The snippet from my bower.json file that lists the versions:

"dependencies": {
  "jquery": "^3.1.1",
  "jquery-ui": "^1.12.1",
  "jquery-migrate": "^3.0.0"
}

At this point I suspect jQuery-UI?

Open up the console in the browser, then expand the notice. Follow the stack trace from the top until you find the first file that isn't jquery-migrate or jquery. For example this issue is in tinymce.js on line 65

migrateWarn @   jquery-migrate-3.3.2.js?cache=da924a:102
get @   jquery-migrate-3.3.2.js?cache=da924a:113
(anonymous) @   jquery.tinymce.js?cache=da924a:65
(anonymous) @   jquery.tinymce.js?cache=da924a:91

The issue was fixed by changing

m.expr[":"]

to

m.expr.pseudos[":"]

Solution 2:[2]

:hidden Selector | jQuery API Documentation has changed it's meaning a little bit. But still works.

Normal programmers are not supposed to touch jQuery.expr.. It is not documented.

Are you using/writing code that creates new selectors? If not, you should not have to worry.
