Runtime Warning: Geometry Proxy - Nested Closure

[ollieatkinson]

Description

When updating state from a nested closure of a GeometryReader the PerceptionRegistrar perceptionCheck incorrectly labels it as isGeometryTrailingClosure.

This was originally observed as I had a gesture onChanged inside of a GeometryProxy.

Checklist

• [X] I have determined that this bug is not reproducible using Swift's observation tools. If the bug is reproducible using the @Observable macro or another tool from the Observation framework, please file it directly with Apple.
• [x] If possible, I've reproduced the issue using the main branch of this package.
• [X] This issue hasn't been addressed in an existing GitHub issue or discussion.

Expected behavior

No runtime warning

Actual behavior

Runtime warning

Perceptible state was accessed but is not being tracked. Track changes to state by wrapping your view in a 'WithPerceptionTracking' view.

Steps to reproduce

Failing Test

@MainActor
func testGeometryReader_GeometryProxyNestedClosure_ImproperPerceptionTracking() async throws {
  struct FeatureView: View {
    let model = Model()
    var body: some View {
      WithPerceptionTracking {
        content
      }
    }
    var content: some View {
      GeometryReader { _ in
        WithPerceptionTracking {
          ZStack {}
            .task { @MainActor in _ = model.count }
        }
      }
    }
  }
  self.render(FeatureView())
  try await Task.sleep(for: .milliseconds(100))
}
