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.

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.
