Saving a file using field at the top of document

Hi there, with the latest update, the ability to click in the file name field at the top of a document (eg Pages, Numbers) to add or change the name of the file, then select filing location, no longer works. Previously, a user could do this and then hit 'return' and it would save to that location with that new file name. It no longer does this. This is a very useful functionality to have. Can it be returned in a future update?
