The Warden doesn't notice us when he's focused on wanting to attack another mob.

In Minecraft Preview Bedrock edition, the warden doesn't notice us when he's trying to attack another mob. In the first video you can see below, the Warden was trying to attack a salmon and I was hitting him making noise, but he never noticed me. He only noticed me when I decided to attack him in front of him as you can see in the second video. I don't know if this also happens in Minecraft Java edition, but if it happens please fix it in both editions. Because this can be an easy way to eliminate the Warden mob. Please fix this if you can.
