Javascript error reported after upgrading to 4.7.6

[raydog153]

After upgrading to the latest tinymce-rails gem with version 4.7.6 and no other code/gem changes I am seeing this javascript error in both development and production:

TypeError: r.jQuery is undefined, jquery.tinymce.self.js:1:111

If I downgrade to 4.7.4 and recompile both development and production seem to work fine. However using 4.7.5 I run into this other reported issue https://github.com/spohlenz/tinymce-rails/issues/234 but only in production mode.
