Redmine

I'm just using redmine on some project (I'm not admin) and was asked to pass it forward, so apologies if some infos are incomplete. But this is a general problem, probably related to this: #3957

The redmine was updated to most recent official version few days ago, and a problem occurred with file uploader.

1) If the "add file" button is not clicked, the file should be deleted from the server.

2) It starts uploading a file after selecting the file, and not after deciding to create the ticket (in earlier version, the file was uploaded after final confirmation on ticket).

Doesn't seem to be configurable, and you cannot cancel a file once it's been uploaded (so it will use server space, even if you don't click the "add" button.
