Loading http://www.webkit.org/misc/drosera/ with the Inspector open will record a timeline. The Timeline is missing the nested timeline data for the main resource. You need to collapse and expand the main resource to see the children rows. See screenshots.

Created attachment 234783 [details] Fixed after collapse and expand
Caused by https://trac.webkit.org/changeset/169735.
Reverting r169735 fixes this. We will then need to find another fix for bug 129696.
Reverting r169735 does not bring the other bug back. I suspect it was fixed by subsequent changes in that area (r170416 & r170389).
