Incorrect values of downloaded and percentage #194
Description
Downloading a large file, result incorrect output of megabytes of downloaded size and current percentage of download.
File that I download: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-11.3.0-amd64-netinst.iso
Total size of the file in ContentLength is nearly 378 MiB however pb shows that it only downloaded 376.79 MiB where it downloaded 378 MiB and same goes with the percentage, it's didn't reach 100% where it should be.
