[BUG] Auto-complete does not work for JSON files!

[SonicandTailsCD]

Describe the bug
It's simple, actually. While typing, for example, "minecraft:, it does not show the possible properties. It's quite tough.
Heck, it won't even show an error after saving, for example, an invalid property: "minecraft:behavior.fart": {}. Obviously that's not valid but unfortunately it won't warn you it's invalid.
So, 2 issues in one.

To Reproduce
Steps to reproduce the behavior:

1. Just make a new file and start writing. Some things will have auto-complete, some won't.

Expected behavior
Auto-complete to actually work and for invalid properties to be flagged, regardless of whether you have to save first.

Screenshots

This isn't supposed to not be flagged.

Desktop (please complete the following information):

• OS: Ubuntu 20.04.6 LTS
• VS Code version: 1.90.0 (can't upgrade)
• Extension version: latest (v8.0.18)

Is this custom entity properties? or an component?

Full file and folder setup would be nice to know

I don't quite get what you mean, but if I were to guess, you're asking me if I'm just testing one component, or an entire custom entity.
The answer to this: "Custom entity". :)

I have VS Code open with both the resource and behavior packs loaded.

Yeah, that's not answering what I asked. There are many ways people load both the bp and rp.

Sorry. I meant, I have both folders loaded in my editor, as in, 2 folders, BP and RP, added to the workspace.

Can you share the full file?

Well, it does this on any file, but sure. Here you go:
