auto complete

Auto complete popup disappears when trying to go up on the 1st item with the up arrow key or trying to go down on the last item with down arrow key. The issue is the same as stated under "issue 1" here.

I've also encountered related info on the dev builds changelog page,: under Build 2161:

• Auto complete: Popup can now be dismissed with the arrow keys

Can there be a fix (a setting for example) which at least offers a way to disable this "feature"? I think it is needed by many people who are trying to learn programming in a language or who don't want to memorize method names or attributes of a language at all.
