Runtime warnings for non-main thread access broken?

[lukeredpath]

I've just discovered a bug in our code where our wrapper around the Apple LinkPresentation framework was completing an effect (using .future) on a background thread. This happens quite frequently as we load link previews but even though I can hit a break point on the runtimeWarning call in the store's threadCheck method, I am not seeing any runtime warnings emitted in Xcode. I am using Xcode 13.3. Has something broken?

We've seen warnings sometimes be delayed a bit, but they still seem to consistently show for us. Could you try in a different project (like maybe even a TCA case study) and see if it happens there too?
