Contributions summary:Isaac contributed to the Ruby on Rails framework by addressing multiple issues and implementing improvements across different areas. They fixed a bug related to MIME type handling in ActionMailer and ActionView. Additionally, they worked on ActiveRecord, allowing it to accept a frozen hash in `as_json` and correcting an issue in association handling, which improved overall functionality. They also made ActiveStorage treat `Rack::Test::UploadedFile` similarly to `ActionDispatch::Http::UploadedFile` and prevented an inaccurate exception within ActionMailer.
