Atto recordrtc (record audio/video) plugin only works in the first editor on a page

This can be tested on any page with more than one Atto editor. Below is just one example, but it is sufficient. Note: audio/video recording is only supported in some browsers. Anyway, given the nature of the fix, it is probably OK to only test in one browser. Go to the question bank in any course. Click Create question, and select 'Description' type. On the form, record some audio or video into the 'Question text'. Verify that it works Now try to record something in the 'General feedback'. Verify that it works Try some other things (e.g. closing the dialogue without inserting the recording; closing the dialogue while recording is in progress, without stopping it.)
