Disabling the expansion of hidden lines in code snippets

[Moxinilian]

Sometimes we make code snippets that contain hidden # lines that setup some context for automated testing and verification but that should not be seen by the reader. However, there is no way to disable the expand button like you can disable the play button with noplaypen.

It would be useful to have a feature like noexpand be available to remove that button without needing to manually inject ugly CSS in the output.
