JSON Schema validation in PhpStorm says the for property is not allowed

[vctls]

That aside, validation works.
The for loop runs fine too, of course.

Example taken from the doc: https://taskfile.dev/usage/#looping-over-tasks

Not sure if it's an issue with PhpStorm in particular, IntelliJ IDEs in general, or an actual problem with the file.
The cmd and for_call sections look fine to me.

I tried validating on https://json-schema.hyperjump.io/ but it seems to be more permissive than PhpStorm.
I can add a bunch of garbage keys without errors.

Also tried this one https://github.com/neilpa/yajsv
But it says the JSON is invalid.

What would be the recommended way of checking the validation?

Nevermind, it's probably a PhpStorm bug.
