What happened?

The 'loadingProgression' value of the useUnityContext hook does not seem to work with gzip compressed unity builds.

My host works fine with non compressed builds and reports load progress as expected.

However, if I try to host a compressed build, loadingProgression will sit at 0 until the zip file is downloaded at which point it will jump to 90. It will load and run the build, it's just not reporting the load progress.

All server side content headers are set as required.
