data-initializer: onProgress: Called inappropriately

[cheako]

From #1031
Example https://gitlab.com/cheako/liluth-ianjeon-rs/-/jobs/12442416558/artifacts/browse/dist/
For me after about 10 seconds the download /completes/ and loading wasm errors on "short read." However the progress bar is updated to %100 and that's not correct. What I expected was to have a partially filled progress bar with the error. What I really want is to retry about 3 times. This webserver has a number of issues like there is no range support, so continue is impossible.
