She was first added to hero labs 4 months ago when the mode was introduced.
To any reasonable person, if an ability says it will do a thing and then in one specific case does not do that thing it is a bug. It does not matter how long its been that way, whether its been in since day 1 or its 1 day old. Abrams has has bugs with his charge since day one that are still not fixed, by that logic they are also intended and he should remain totally inconsistent in how he works because he was introduced that way.
If something doesn't perform the way the game tells you it will perform, it is a bug, either in that its unintended or that the game is not communicating to the player that it is intended.
