Inconsistent result when writing negative float into int32

[MonteePoke]

Minimal code to reproduce:

import {Field, Message} from 'protobufjs';

export class DataPacketCacheDto extends Message<DataPacketCacheDto> {
    @Field.d(1, 'float')
    f: number;

    @Field.d(2, 'int32')
    f2: number;

    @Field.d(3, 'int32')
    f3: number;
}

const message = new DataPacketCacheDto({
    f: 1097.300048828125,
    f2: 1.793662034335766e-43,
    f3: -2.0975153105823492e-14,
});

const buffer = Buffer.from(DataPacketCacheDto.encode(message).finish());

console.log(buffer.toString('hex'));

const decodedPacket: DataPacketCacheDto = (DataPacketCacheDto.toObject(DataPacketCacheDto.decode(buffer as Buffer), {
    defaults: true,
}) as DataPacketCacheDto);

console.log(decodedPacket);

Expected result:
Error: invalid wire type

Actual result
Every run outputs a different result:

1. Trying to encode results in error:

            throw Error("invalid wire type " + wireType + " at offset " + this.pos);
                  ^
Error: invalid wire type 4 at offset 11

2. Some runs manage to encode message into a buffer, but the buffer can't be decoded:

0d9a298944100018008ab8346c0100008891

E:\Projects\protobuf_test\node_modules\protobufjs\src\reader.js:13
    return RangeError("index out of range: " + reader.pos + " + " + (writeLength || 1) + " > " + reader.len)
;
           ^
RangeError: index out of range: 13 + 108 > 18

3. Other times decoding the buffer succeeds but, field values aren't the same as before encodingOutput:

0d9a2989441000180000000034090000c8c0
{ f: -6.25, f2: 0, f3: 0 }

Observations:

• positive float are rounded;
• buffer is simingly random;
• indexes in error messages are random;
