Summary

I have fixed an issue where the display of the HIR diff in the React Compiler Playground was incorrect. The HIR diff is supposed to show the pre-change state as the source, but currently, it is showing EnvironmentConfig as the pre-change state. This PR corrects this by setting the pre-change state to source instead of EnvironmentConfig.

How did you test this change?

Thanks for the PR! I’ve never actually used the diff mode for the HIR panel, because there is nothing to diff against. Would you mind changing to just make the diff source empty for this panel? Diffing against the source doesn’t make sense since they’re such different representations.

Thank you for reviewing the PR! I have updated it so that the HIR diff is no longer displayed.
