Guardians never drop fishing loot

The bug

Guardians are intended to randomly drop fishing loot. In fact, it's right here in the loot table:

{
    "conditions": [
        {
            "condition": "killed_by_player"
        },
        {
            "condition": "random_chance_with_looting",
            "chance": 0.025,
            "looting_multiplier": 0.01
        }
    ],
    "rolls": 1,
    "entries": [
        {
            "type": "loot_table",
            "name": "loot_tables/gameplay/fishing/fish",
            "weight": 1
        }
    ]
}

This does NOT work, because the name is missing the .json extension that for some reason is included in Bedrock Edition, as seen in other referential loot tables such as vindicator_raid.
