Steps to reproduce:
1. Open https://build.webkit.org/dashboard/
2. Hover any failure bubble
3. Move mouse pointer over the popover that appears
Results: The popover disappears immediately, so you can't click any links. Also, it appears without a delay in the first place.
Dean, is this not expected to work any more?
