Research direction
Look at PR #6791 to understand the ImageStore type mismatch diagnostic that was added. Then identify the existing snapshot test file for diagnostics (likely under tests/ directory) and add a test case similar to existing ones. The test should verify that the diagnostic is emitted correctly. No code change beyond adding the test is needed.
