The output element is a labelable element and as such, its naming algorithm should be updated to indicate this.

Presently the algorithm is:

1. aria-label and aria-labelledby
2. subtree
3. title
4. no name

Should be updated to:

1. aria-label and aria-labelledby
2. name from label element
3. title
4. no name

edit: subtree shouldn't be considered for name. name AND subtree need to be announced by the output live region and should not just announce name.
