Description
There are some operations that yield proxies which do not match the data they produce at runtime. We should add tests that verify proxies match, and fix the operations where they dont.
Imported from Jira [BEAM-12379](https://issues.apache.org/jira/browse/BEAM-12379). Original Jira may contain additional context.

Contributor guide
Research direction
Start by locating the DataFrame operation implementations and any existing proxy-related tests. Reproduce cases where a proxy does not match the runtime data, then add coverage for those operations and fix the mismatches. Done means the tests verify that each proxy matches the data produced at runtime.
