Polar Bears Attacking Through Walls

I was playing unmodded, singleplayer minecraft. I was located in a snowy village when a polar bear became hostile due to it having a baby nearby. I rushed into one of the village houses and stood in the corner of the house. Even though the corner was constructed out of entirely full blocks, I was still somehow hit and killed. After I respawned, the bear was still angry, so to test this glitch I went into another house and the same thing happened. To create this issue, simply anger a polar bear and put a one block wall between you and it. If it goes anything like mine did, the polar bear should be able to hit you if you stand right next to the wall. It must be some glitched attack box or something- but it could just be me. Please comment if you test this out and the same thing happens.
