Steps to reproduce

Uncomment line 5 in example.

What is expected?

Provide a computed property that gets value from global properties.

What is actually happening?

Referencing computed in provide breaks it's reactivity.

Any additional comments?

Can be resolved by

provided: computed(() => this.test)

you provided the return value from the computed property, so yes, that can't be reactive. That's not a bug.

Your proposal how to resolve this is actually the documented way to go:
