Comment (by dmethvin):

 The best solution would be for Wordpress to not use Migrate as a
 production tool. Since Migrate imperfectly tries to introduce deprecated
 behavior back into newer versions of jQuery, the result is a bit of a
 Frankenstein's monster that isn't the same as the version of jQuery that
 appears to be running.

 If there are things the jQuery team can do to help move Wordpress to a
 newer version of jQuery let us know. It appears Wordpress no longer needs
 support for browsers older than IE11, if that's the case it should be
 possible to use jQuery 3.3.1 which supports browsers back to IE9. Does
 Wordpress itself need Migrate, or is it for the benefit of older themes?
