Description
Some datasets, particularly this one:
https://openml.org/data/v1/download/16797613/CIFAR_10.arff
Have lately been yielding incomplete files when downloading them, whether through a web browser or through API using scikit-learn's fetch_openml.
For example, back a few months ago, this dataset was yielding a 600mb+ file like this:
But if I download the same dataset through a web browser today, I get files of different sizes:
The download reports completing successfully on both web browsers and scikit-learn's fetch_openml, despite not fetching the full file.

Research direction
Start by reproducing the download from the linked OpenML URL and through scikit-learn's fetch_openml, then trace the download endpoint in the TypeScript application. Check how response completion and file size are validated; done means incomplete downloads are detected and reported as failures rather than successful fetches.
