Cloning does not work on available download bandwidth changes

Started to clone big git repo on not-too-fast, _stable_ VDSL link (up to 20mbps down)...

     $ git clone https://github.com/googleapis/google-api-go-client
     Cloning into 'google-api-go-client'...
     remote: Enumerating objects: 644446, done.
     remote: Counting objects: 100% (6922/6922), done.
     remote: Compressing objects: 100% (2904/2904), done.
     Receiving objects:   0% (3859/644446), 20.82 MiB | 1.01 MiB/s

...and then started to watch a VOD movie on same link; when VOD buffers data, eats almost all available down bandwidth and leaves only about 100 kB/s for git...

     Receiving objects:   1% (7111/644446), 44.49 MiB | 130.00 KiB/s

...and when VOD stops buffering and whole bandwith is available for git again, git transfer starts to grow...

     Receiving objects:   1% (7660/644446), 50.56 MiB | 575.00 KiB/s

...but finally git throws an error

     error: 181 bytes of body are still expected5 MiB | 1015.00 KiB/s
     fetch-pack: unexpected disconnect while reading sideband packet
     fatal: early EOF
     fatal: index-pack failed

or sometimes:

     error: RPC failed; curl 92 HTTP/2 stream 5 was not closed cleanly: 
CANCEL (err 8)
     error: 6109 bytes of body are still expected
     fetch-pack: unexpected disconnect while reading sideband packet
     fatal: early EOF
     fatal: fetch-pack: invalid index-pack output

No such problems when downloading bigger file (i.e. linux kernel source) with wget or curl instead of git clone (wget/curl transfer drops to about 100 kB/s when VOD buffers and increases to full speed when VOD is not transferring and transfer finishes successfully).

Sounds like a bug in git; should not throw an error on available download bandwidth changes as wget and curl do and should not require any params tuning (to stop users flooding bugtrackers).

git versions tested:

     // Debian 11, amd64
     $ dpkg -s git | grep Version
     Version: 1:2.30.2-1+deb11u2

     // Debian 12, amd64
     $ dpkg -s git | grep Version
     Version: 1:2.39.2-1.1
