Cannot open Child Segment from within parent Segment



When dealing with a Segment that has child Segments, one must be able to click the small magnifying glass next to the child Segment name in order to open up that Segment in a new tab.

When clicking on the magnifying glass, however, user receives an error.

When attempting to open that same child Segment from the regular navigation bar, it opens with no error.
