Deferred .then() now works asynchronously in jQuery 3.x. As a result, it seems that the order of XUI processing was broken and problems began to occur.

The upgrade guide says as follows:

Another behavior change required for Promises/A+ compliance is that Deferred .then() callbacks 
are always called asynchronously.
Previously, if a .then() callback was added to a Deferred that was already resolved or rejected, 
the callback would run immediately and synchronously.
