Added several tests (https://codereview.chromium.org/1798993003/) but have not yet been able to reproduce this behavior. It's possible that it only occurs in the case where analyzer is recreating a resolved AST when the element model already exists.

This bug is so old, I think we'll just have to re-open if we se again, since it doesn't have a good reproduction.
