Wrong result while quering by $in with an index on a large numeric string property

my code:

    let t;

    let alarms = [];
    for (let i = 0; i < 10000; i++) {
        alarms.push({id: "74590869096" + (907836 + i), name: 'hello' + i});
    }

    let db = new loki('exampleDB');
    let alarmCollection = db.addCollection('myAlarms', {indices: ['id']});

    console.log(`开始插入。。。`)
    t = Date.now();
    alarms.forEach(obj => alarmCollection.insert(obj));
    console.log(`完成插入 耗时${(Date.now() - t) / 1000}s alarmCollection.count=${alarmCollection.count()}`);

    let exampleId = "74590869096907841";
    console.log('find by id', alarmCollection.count({id: exampleId}))
    console.log('find by $in', alarmCollection.count({id: {$in:[exampleId]}}))
    console.log('find by $keyin', alarmCollection.count({id:{ $keyin: { [exampleId]: 'anything'} }}))

result:

开始插入。。。
完成插入 耗时0.045s alarmCollection.count=10000
find by id 1
find by $in 13
find by $keyin 1

This collcetion has an index on id, which is a large numeric string property. As we can see, while i count/find, $keyin can return correct result, but $in returns Wrong result.
