False positive of extension_access_modifier on property with private(set)

Describe the bug

When a public extension has a single property with private(set), the property receives a warning that it should use an extension access modifier.

This isn't possible since private(set) cannot be moved from the property to the extension.

Complete output when running SwiftLint, including the stack trace and command used
