Admin UI doesn't handle very long strings well.

Steps:

1. Create a content item with a long string (e.g. 255 characters) in ezstring.
2. Check the Dasboard. (https://recordit.co/nZ4R2p9qnd)
3. Check the item in Content / Content structure. (https://recordit.co/ciSx05NhO5)

Actual: Scrollbars appear and text goes outside of view.
Expected: Maybe ellipsis and full value in toolbar.
