Effect the updated version of IE11

  • IE11 updated versions: 11.0.5 is working as expected.
  • IE11 updated versions: 11.0.33 is effected. (latest updated version for now). (also tested 11.0.32 is effected as well.)


Comments and activity

  • I understand frameset and frame are obsolete in html5
    It is broken between IE11 updated versions: 11.0.5 and IE11 updated versions: 11.0.33. It should be treated as bug.
