Checkboxes/Radios with description display set to "before" renders description in #prefix

A markup change like this could make layout changes in cases of customization. So, I doubt this change will be made in 6.2.x.

Please fix the coding standards issues. Why is the test change needed?

@liam-morland
You're absolutely right that a markup change like this could affect customized layouts, so I agree it likely shouldn't go into 6.2.x. Still, it's helpful to have the patch available for anyone who wants the corrected behavior prior to updating to 6.3.

The test change was probably an artifact of resolving merge conflicts — I’ll double-check and clean that up along with the coding standards. Thanks for the catch!

Should be ok now, 615 targeting 6.3.x and 616 targeting 6.2.9

Here is the change record. With tests passing, I am fine with merging this.

Since we are changing the $form array, this should be only committed to 6.3.x
