Deleting wall post, "Yes" button doesn't have button background

[Kristina Hoeppner]

When you post on somebody else's wall and then delete your post, the "Yes" button on the "Delete" page doesn't have the normal button background and outline. We are just using the normal button color (grey) rather than primary button color.

To replicate:

1. Have 2 people on your site.
2. Log in as PersonA.
3. Post on Person's B wall.
4. Click the "Delete" icon on your own wall post that you just made.
5. You are taken to the page where you need to confirm the deletion.
Expected result: The "Yes" button is an actual button. The "Cancel" link is correct.
Actual result: There is no button outline and background behind "yes".
