Year template goes wrong before the date 1894-01-01

I tried to create a heatmap with with a data source

data :{source: [{date:new Date('1893-12-01'), value:1}]}

in the following template setting

domain: {type: 'year'},
subDomain: {type:'month'}

The result on the year label will goes wrong (1893 will turn into 1892) and if the date is "1832-10-01". Then the Tooltip of that month will also goes wrong.

Here is the sample html can reproduce the problems.

    </head>
    <body>
        <div id="cal-heatmap"></div>
        <script>
            const data = [{date: new Date('1832-10-01'),value:10}
            // ,{date: new Date('1893-04-01'),count:10},{date: new Date('1893-12-01'),count:10},{date: new Date('1894-01-01'),count:1}
        ];
            const cal = new CalHeatmap();
            cal.paint({
    locale: 'en',
    animationDuration: 0,
  itemSelector: `#cal-heatmap`,
  range: 12,
          date: {start: new Date('1832-10-01'),
          min: new Date('1832-10-01'),
          max: new Date('1894-04-01') },
  domain: { type: 'year' },
  subDomain: { type: 'month', label: '', width: 7, height: 45, radius:10 },
  scale: { color: { type: 'linear', scheme: 'Reds', domain: [0, 50] } },
  data: {
        source: data,
        x: 'date',
        y: 'value',
        defaultValue: null,
        groupY: 'sum'
      }
}, [[Tooltip, {text: (timestamp, value, dayjsDate) => `${value || 0} - ${dayjs(timestamp).format('YYYY-MM')}`}]])
        </script>
    </body>
