I think this is a reasonable fix. @IgorMinar @caitp thoughts?

[caitp]

On the surface it looks okay, for the use case which is tested, but I'd prefer if some other test cases were added to verify other ways it might be used. That's just my feeling based on a quick glance at the diff, though

[IgorMinar]

otherwise it looks good to me

@IgorMinar done, amended commit.
