Steps to Reproduce

const response = await fetch('https://lf9-dp-fe-cms-tos.byteorg.com/obj/bit-cloud/stocks.json');
const data= await response.json()
console.log(data)

const spec = {
  animation:false,
  type: 'line',
  sampling:'lttb',
  samplingFactor:0.1,
  // brush:{
  //   visible:true,
  //   updateElementState:false,
  //   zoomAfterBrush:true
  // },
  // dataZoom:[
  //   {
  //     orient:"bottom",
  //     showBackgroundChart:false,
  //     filterMode:"axis"
  //   },
  //       {
  //     orient:"left",
  //     showBackgroundChart:false,
  //     filterMode:"axis"

  //   }
  // ],
  data: {
    values:  data  },
  title: {
    visible: true,
    text: 'Stacked line chart'
  },
  stack: true,
  xField: 'Date',
  yField: 'Close',
  seriesField: 'Symbol',
  line: {
    style: {
      curveType: 'monotone'
    }
  },
  point: {
    style: {
      size: 0,
      fill: 'white',
      stroke: null,
      lineWidth: 2
    },
    state: {
      dimension_hover: {
        size: 10
      }
    }
  },
  legends: [{ visible: true, position: 'middle', orient: 'bottom' }]
};

const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();



// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;

开启samplilng，鼠标hover到dimension上，移走后point不会消失。仅在2.x复现，1.x是正常的

Current Behavior

Expected Behavior

points will disappear normally

Any additional comments?

No response

Start with the supplied TypeScript VChart reproduction using a line chart, sampling:'lttb', and point dimension_hover state. Investigate how hover state is cleared after the pointer leaves the dimension when sampling is enabled, comparing the 2.x behavior with the stated 1.x behavior. Done means the point disappears normally after hover ends.
