This is not clear why we check only first checkbox?
What about the cases when we ask user to check boxes which labels does not have a letter?

Actually this is correct, that we do not allow elements with the same name. I believe this is by RFC. Though I could be wrong, because I did not work with checkbox/radio a lot.

Description
Replaces #2000 and #2431 with simpler logic, and I believe that .elements() should return all of the eligible elements.
Previously, if you had 2+ inputs using name arrays, such as:
It would only hit validation on the first input in the array, allowing all the remaining inputs with the same name to remain empty.
Technically, I'm pretty sure the following, without using [] syntax would have the same problem:
I'm not familiar with the testing framework, but please review the idea behind this PR first, and if you're confident that it will be merged if tests are included, I'll dig deeper into testing.
