Close button does not cancel an edit

When the Close button is clicked the edit session ends, however, the system throws a message when next editing stating that the previously discarded edit was saved as a draft and now needs to be viewed or discarded.

This is an example of the message thrown after an edit is "closed":

A version of this page you were editing at 15 May, 2015 12:54 was saved as a draft. Do you want to view the change,  resume editing or discard it?

Steps to reproduce:
1) Edit an existing Confluence page in OnDemand
2) Type some text
3) Click the Close button
4) Debate whether or not 'close' means 'Cancel' or 'Close the editor' or 'Close and save a draft' or 'Close the editor and perhaps do something in the background'
5) Click Edit button

A message may be thrown saying that a version of this page was saved as a draft.

Strongly suggest changing the name of this button to 'Cancel' - if indeed that is what this button does.
