Failing CasperJS test

[nicolaasmatthijs]

The following CasperJS test seems to be failing consistently:

# Verify formatting a comment
FAIL Links are correcty formatted
#    type: assertSelectorHasText
#    file: node_modules/oae-core/comments/tests/comments.js:154
#    code: test.assertSelectorHasText('.comments-level-0 .media-body .oae-markdown p:nth-of-type(1) a', 'Absolute Link', 'Links are correcty formatted');
#    subject: false
#    selector: ".comments-level-0 .media-body .oae-markdown p:nth-of-type(1) a"
#    text: "Absolute Link"
#    actualContent: ""
