As you can see in the attached screenshot, the horizontal line beneath the workboard header seems to tear at the workboard column boundaries.
This is on firefox `39.0`. It looks fine in chrome.
My install is at head as of a few minutes ago:
```
Phabricator Version
bb54957d9687a9278caae41b2f0918de548254a6
Arcanist Version
999eb93765688a788b77513334cc9a651726c94b
libphutil Version
aa6cd8f7e5e5e637dcfcb8417fbc343b45820c93
```
I do not see this issue on secure.phab, but I know you guys aren't always running head here.
