CoPilot consistently removing code when generating method summaries on void methods.

I've been using the new Agent mode with both Sonnet 3.7 and GPT 4.1. With both models, method summaries will generate fine as long as you are only generating summaries for methods with a return value.

Any attempt to generate a summary for a void method causes all void methods to be removed, including if they get picked up when asking to have all public methods summarized.

This happens even when directing the model not to remove any code, and when telling it that the output should have more lines than the input (in one case it told me the output had more lines when it had many fewer).

Has anyone else run into this? If so, have you found a way to get it to generate the summaries?
