Steps to reproduce:
1) Go to https://stat-info.cz/safari-sw-download-tests.html
2) Start download using Test #1

Download manager now shows 0 kB target file size during the download. It doesn't respect Content-Length header sent from ServiceWorker via Response.

Reproducible on iOS 16.4, 16.2 and 16.1.
Working fine on iOS 15.7.
Working fine in Safari 16.4 on macOS 13.3.1.
