replayer.play makes page stop working

code like this:

mounted() {
        const self = this;

        this.events = [];
        this.record = rrweb.record({
            emit(event) {
                console.log(1);
                self.events.push(event);
            }
        });
    },
    methods: {
        stopRecord() {
            this.record();
            setTimeout(()=> {
                const replayer = new rrweb.Replayer(this.events);

                replayer.play();
            }, 2000);
        }
    } 

I do some actions, then stop recording and use replayer.play. Then the page stops working,as the picture shows. no console errors

@liswift Good news! If you are interested in dig into which extension has a conflict, it will be nice to contribute the information to an FAQ doc.
