Flatpickr default system tests fail when scaffolded.

I’m wondering if we should default JSP’s flatpickr to use flatpickr_allow_input: true  so that system tests and the like can be managed easier. What do you guys think? Is there a better way to write tests for this or is this really the best option. More thoroughly documented here. At very minimum we could resolve this issue for those using JSP by implementing this fix, or maybe there's a better fix that I am not aware of.
