This test continues to validate the pre element.
The spec states:
"A newline in a pre element should separate paragraphs for the purposes of the Unicode bidirectional algorithm. This requirement may be implemented indirectly through the style layer. For example, an HTML+CSS user agent could implement these requirements by implementing the CSS 'unicode-bidi' property."
This reftest passes if below you see "ABC ABC" repeated on two separate lines below (4 ABCs total):
CBA CBA ABC ABC
