Edit content details issues

I'm seeing a number issues with the Edit Content Details modal.

- In Firefox, I'm sometimes not able to make changes or use the next and previous arrows when inside the title field. This is intermittent, and is easiest to reproduce when selecting a word in the title
- In Chrome, hitting the next and previous arrows cause the `Save` button to become enabled.
