What version are you running?
2.2
What's the URL of the page containing the problem?
r/473/
What steps will reproduce the problem?
1. Open an existing review
2. click on the summary text -> opens an input field
3. change the summary
What is the expected output? What do you see instead?
For the other fields (description, testing, ...), there is a pair of OK/Cancel buttons appearing when you start editing them, but not for this field. That makes impossible to edit only the summary since the "publish changes" button never appears.
The Javascript console doesn't show any error and the DOM doesn't show the missing buttons either.
What operating system are you using? What browser?
Ubuntu 14.04, chrome 35.0.1916.153
