This is the only failure I found in the test suite with jQuery 3.0 and it's easily fixed.
jQuery 3.0 uses Promise/A+ compliant .then method which is always async. The older .done and .fail methods are still sync. Ref: https://jquery.com/upgrade-guide/3.0/
It's not clear why these two tests use Deferred at all since they appear to be completely synchronous. The giveaway is that there is no QUnit assert.async() call in the test, which you would need if there was any async component.
