Summary:
At some point, the highlighting behavior for the timeline broke. When you follow a link to a particular timeline story, the story should be highlighted.
Prior to this change, the `<a />` tag itself highlights, but there's no associated CSS and it's too deep in the tree to do anything useful.
(Since this change is fairly straightforward, I gave up digging for the root cause before finding it.)
Test Plan:
- Clicked a timeline story anchor, saw the story highlight.
