"too much recursion" with jQuery 3.4 using enum

[brockfanning]

This issue is easily fixed by using another version of jQuery other than 3.4 (like going up to 3.5.0 or going back to 3.3.1) but I thought I would post it here in case anyone else ran into it. Feel free to immediately close this - I just wanted it to be searchable.

This is a weird bug, but it really seems to happen... If using jQuery 3.4, and a field has an "enum" with 3 or fewer items, Alpaca fails with "too much recursion". Changing the enum to four or more items fixes the problem. And as mentioned above, changing the jQuery version also fixes the problem.
