Steps to Reproduce:

1. hover on imported object and the tooltip shows
2. two problems: the file header is not from the imported one; it's at the bottom of the content, expected to be on the top of the tooltip;

This is a limitation of how our JS Doc support is designed. JSDoc comments are merged into the next declaration (this issue is similar to microsoft/TypeScript#15106).
