Actual result

see also: #279 and w3c/aria-practices#78

IE

  • addtions: "is message" = Only the element nodes are output.
  • text: "This a" = Only the text nodes outside of element nodes are output.
  • all: "removed This is a message" = everything is output, "removed" because of one space inside div element

Chrome

additions, text, all: "This is a message" = everything is always output, aria-relevant is ignored

Firefox

additions, text, all: "is message This is a message" = first the element nodes are output, then the entire text content, aria-relevant is ignored
