The fast/images/animated-gif-body-outside-viewport.html and fast/images/animated-gif-window-resizing.html layout test are time out since they were added on r177927 (http://trac.webkit.org/changeset/177927).
Committed r194270: <http://trac.webkit.org/changeset/194270>
These have both been flaky for some time; marked them accordingly in r194270.
