Video permission dialog doesn't reflect state of collection permission

[pdpinch]

Steps to Reproduce

1. Create a collection and add a video (or use an existing one)
2. Set the collection permissions to "Only Owner"
3. Click the overflow button on a video and choose "Edit" from the pop-up menu
4. Confirm that under "Who can View this collection" the choice "Same as Collection" has a hint "Only Owner"
5. Return to the collection permissions and change them to "MIT Touchstone"
6. Click the overflow button on a video again and choose "Edit" from the pop-up menu

Expected Behavior

• Since the collection permission is now "MIT Touchstone" the expectation is that the "Same as Collection" hint on the video will also say "MIT Touchstone"
• is this just a display issue, or is the permission on the video actually incorrect?

Actual Behavior

The video permission for "Same as Collection" has the hint "Only Owner"
