this lgtm! I have tested this and it solves the problem. Probably needs to be rebased before merge.

@epicfaace I have reviewed this PR and added my comment above.

Thanks for the change @saimanoharnethi, and thanks for reviewing, @newt10 -- one thing is that it would be great if you could add a test that tests the specific issue in #2102 so we can make sure this issue doesn't regress in the future.

@epicfaace , I am closing this in favor of #2536 . I have added tests to #2536 to prevent future regressions. Since the author has not gotten a chance to update the PR, we can go ahead with #2536 for addressing the issue.
