Looks good to me! Please rebase once #2418 is merged, and then ensure this PR also passes all of CI.

Can we merge it now? or waiting for a fix to this bug?

I think it can be merged while that fix is in progress, since it passes all of the newly added tests in CI and none of those models would invoke this specific converter.
