Steps to Reproduce

option = {
    timeline: {
        data: ['9月1日', '9月2日', '9月3日'],
        axisType: 'category',
        show: true,
        autoPlay: true,
        playInterval: 1000,
        lineStyle: {
            show: false
        }
    },
    options: [{
        tooltip: {
            'trigger': 'axis'
        },
        calculable: true,
        xAxis: [{
            'type': 'category',
            'axisLabel': {
                'interval': 0
            },
            'data': [
                '1', ' 2', '3', '4', '5', '6', '7', '8'
            ]
        }],
        yAxis: [{
        }, {
            'type': 'value',
        }],
        series: [{
            'yAxisIndex': 1,
            'type': 'bar',
            'data': [5, 6, 8, 28, 8, 24, 11, 16],
        }]
    }, {
        title: {
            'text': '9月2日'
        },
        series: [{
            'data': [45, 43, 64, 134, 188, 43, 109, 12]
        }]
    }, {
        title: {
            'text': '9月3日'
        },
        series: [{
            'data': [110, 32, 111, 176, 73, 59, 181, 9]
        }]
    }]
};

Current Behavior

Set the show property of linestyle to Timeline. show = false. After you click checkpoint, drag and release the pointer. Error: Cannot read properties of undefined (reading 'shape'), after which the timeline component fails to select any location.

This bug is not present in versions 4.9.0 and earlier, and is present in versions 5.0.0alpha.1 through 5.3.3.

Expected Behavior

Click Checkpoint and drag，the timeline works normally
