I've followed all the steps that are needed for enabling jQuery integration (I have the latest versions of @ember/jquery and @ember/optional-features installed and in package.json; have "jquery-integration": true in optional-features.json) but I still see a warning in the console when accessing originalEvent. I see the following check:

return EmberENV._JQUERY_INTEGRATION === true;

Which returns false in my case as EmberENV is:

{"FEATURES":{},"EXTEND_PROTOTYPES":false,"_APPLICATION_TEMPLATE_WRAPPER":false,"_TEMPLATE_ONLY_GLIMMER_COMPONENTS":true}

I think _JQUERY_INTEGRATION defaults to true and perhaps it is being removed from the hash because it has the same value? If this is so, the code above should be changed to:

return EmberENV._JQUERY_INTEGRATION !== false;

Am I missing something?

P.S. Ember 3.3.1 and latest Ember CLI.
