For some reason, only some items in the product nav menu can be right-clicked. For example,
If in Analytics, Analytics and Target can be right-clicked to Open in New Tab.
Activation cannot be right-clicked.
All the other Core Services can be right-clicked.
But if you're in Target, everything you right-click and open in a new tab actually just opens Target in the new tab.
If you're in the Core Services and right-click, the behavior is unreliable.
Would be great to make this more consistent across the Marketing Cloud.
