Bug description

A couple tests fail with:

Message: 
System.InvalidOperationException : Code fix is attempting to provide a fix for a non-local analyzer diagnostic

  Stack Trace: 
DefaultVerifier.False(Boolean assert, String message)

These are the tests that fail:

TransitiveNoCheck_InCtor

Repro steps

Enable the tests and run them.

Expected behavior

Tests should pass.

Actual behavior
