Test of Firefox’s new showlongdesc action

The tests

The first test has a visible link that has aria-hidden="true"
The code:

  <!DOCTYPE html><title>test 1</title>
  <img aria-describedby=longdesc src=http://dev.w3.org/html5/alt-techniques/images/shalott.jpg alt='The Shallot image.' >
  <p aria-hidden=true><a id=longdesc href=page2>Read more.</a>

The second test has a link that has been made hidden with the hidden attribute.
The code:

  <!DOCTYPE html><title>test 2</title>
  <img aria-describedby=longdesc src=http://dev.w3.org/html5/alt-techniques/images/shalott.jpg alt='The Shallot image.' >
  <p hidden aria-hidden=true><a id=longdesc href=./>Read more.</a>

Things to look out for

Does the text of the link get announced?
Is the link presented as description link?
