Comment (by SergeyBiryukov):

 > The button is a simple link with a `javascript:history.go(-1)` hack.
 This should instead be a form with hidden values that submits back to
 setup-config.php?step=1, and fills out the form so they can try again.

 This would resolve #24836.

 > Additional enhancement: If the prefix is malformed (can only contain
 letters, numbers and underscores), we do a wp_die(). We should again have
 a form with a 'Try Again' button that returns them.
