Bombshell No Vision Scouting Intended?

[Logitre]

Hi, I'm new to this game and came across a feature of the bombshell that I'm not sure if is intended by the developers.

As a sieged-up bombshell, it cannot attack if there are no enemy units within splash range. However, when there is an enemy unit just in the fog of war 4 tiles away (with no other units granting vision), the bombshell is able to attack even if the bombshell cannot see the enemy. The splash icon, in fact, essentially reveals enemy units in the fog of war like a radar does in the 4th tile from the bombshell.

Is that intended?
