Fix#4103
[#4133] fix test failure

- Default locale included ante/post meridiem marker, which select
  element was not taking into account, nor were tests, which left a
  dangling " a" following the markup, and hence a failing test. Updated
  code to strip such a format marker as well as trim the final markup.
