The text description for the Bedrock entity behavior component, minecraft:ignore_cannot_be_attacked is identical to the the text description for minecraft:cannot_be_attacked. This must be a mistake because it two components with contrary functions should not be doing the exact same thing.
See https://learn.microsoft.com/en-us/minecraft/creator/reference/content/entityreference/examples/entitycomponents/minecraftcomponent_ignore_cannot_be_attacked?view=minecraft-bedrock-stable and

I found it very odd to, and you’re not the only one I hope it resolve soon!
