That’s an excellent idea @Thorsten.Michel . Sadly, I can’t reproduce it. Inspecting the names being compared, they do indeed have some truncation, but they are truncated the same way for both versions, and the comparison passes. We should probably switch the names being compared to hashes or something similar at some point.
If it doesn’t resolve and becomes a concern, please feel free to create an issue on the MTM repository. For possible future reference, the comparison uses data retrieved from the TagManager.exportContainerVersion API endpoint for the previous and draft versions.
