Can Http.Receiving not handle data that is more than 1023 byte?

[koji-k]

I am trying to track size of received data of http response (Http.Receiving).

Elm codes works fine.
But size of Http.Receiving seems to have a problem.

Specifically, size of Http.Receiving will be set Nothing when Content-Length is more than 1023 byte.
If Content-Length smaller than 1024 byte, it is no problem.

I think event.lengthComputable returns false when Content-Length more than 1023 byte.
But i don't know why realize so...

https://github.com/elm/http/blob/master/src/Elm/Kernel/Http.js#L183

I wrote following debug print function execute in update.

printProgress : Http.Progress -> String
printProgress progress =
    case progress of
        Sending record ->
            "Sending: sent=" ++ String.fromInt record.sent

        Receiving record ->
            "Receiving:"
                ++ " received="
                ++ String.fromInt record.received
                ++ ", size="
                ++ (Maybe.withDefault -1 record.size |> String.fromInt)

Result of response with 1023 byte:

• Chrome: Receiving: received=1023, size=1023: (Loading,<internals>)
• Firefox: Receiving: received=1023, size=1023: (Loading,<internals>)

Result of response with 1024 byte:

• Chrome: Receiving: received=1024, size=-1: (Loading,<internals>)
• Firefox: Receiving: received=134, size=-1: (Loading,<internals>)

received has problem too on Firefox.

Is there something workaround?
