The actions bar for review requests had a minimum height set, but it was 1 pixel too small. Most of the time this doesn't matter because the actions set the height, but in the case of viewing a review request that doesn't have a diff anonymously, the actions bar is actually completely empty. This resulted in the tabs being shifted down one pixel. Testing Done: Opened a private browser window and looked at a review request that didn't have a diff. Saw that the review request tabs were no longer misaligned.
