Zombie banging on door subtitle is called "Block broken"

The bug

When a zombie bangs on a door, the subtitle is called "Block broken" (subtitles.block.generic.break).

This is caused by the entry in the sounds.json file:

"entity.zombie.attack_door_wood": {
    "sounds": [
        "mob/zombie/wood1",
        "mob/zombie/wood2",
        "mob/zombie/wood3",
        "mob/zombie/wood4"
    ],
    "subtitle": "subtitles.block.generic.break"
},
"entity.zombie.attack_iron_door": {
    "sounds": [
        "mob/zombie/metal1",
        "mob/zombie/metal2",
        "mob/zombie/metal3"
    ],
    "subtitle": "subtitles.block.generic.break"
}
