Trident thunder sound definition schema error

In the sound event "item.trident.thunder", the field "volume" is located in the root of the sound definition, instead of in each sound entry. This sound event is defined in the "vanilla_1.20.20" resource pack.
Given that the volume is ear-piercingly loud when actually 1000.0, as shown in the video and resource pack, it should not actually be 1000.0 anyway.
