AI Bug - Wizard attacking defending Lavahound above Walls bugs

When defending lavahound fly and stay exactly above a wall unit at the same time wizard attacking the defending lavahound will cause wizard splash damage to destroy the wall unit below the defending lavahound.

I believe this isn't how the AI intended to be, this bug cost me the 3star attck and I get only one star because my golem went not where I planned it to go because unessary wall suddenly destroyed due to wizard splash damage when they attacking lavahound in the air.

On top of that, its look so ugly if we imagine wizard splash damage AOE will look like a long cylinder. Its kinda illogical how high the troop in the air will share splash damage that so far away with building in the ground.

If possible later I will attach picture or maybe video of the scenario.
