This was a bit misleading before - validLengths meant counts of valid numbers of digits, not including the gaps, so where this was used relied upon some implicit logic to strip out non-numeric characters first. This didn't work well when checking if the mask was satisfied from TextElement to set the new isMaskSatisfied flag. Changed this to track number of gaps before passing in valid lengths into the mask.
