Steps to Reproduce

{
  series: [{
        name: ' xxx',
        sampling: 'lttb',
        type: 'line',
        emphasis: false,
        showSymbol: false,
        symbol: 'circle',
        symbolSize: 10
      };
  }]

Current Behavior

鼠标hover的series会被渲染在最上层，即使emphasis被设置为false, 这导致当图表中有多条折线且为密集数据时，用户一旦移动鼠标，多条折现会来回被渲染在最上层，视觉效果为快速闪动，体验较差

Expected Behavior

emphasis关闭后，能够取消所有默认效果

**TITLE** [Bug] When there are multiple polylines in a chart and are dense data, even if the emphasis multiple polylines are turned off, they will be rendered back and forth at the top **BODY** ### Version 5.2.2 ### Link to Minimal Reproduction _No response_ ### Steps to Reproduce ```js { series: [{ name: ' xxx', sampling: 'lttb', type: 'line', emphasis: false, showSymbol: false, symbol: 'circle', symbolSize: 10 }; }] ``` ### Current Behavior Mouse cover's strings will be rendered at the top, even if the emphasis is set to false, which results in when there are multiple polylines in the chart and dense data, once the user moves the mouse, multiple discounts will be rendered back and forth at the top, the visual effect is fast flashing, the experience is poor ### Expected Behavior When emphasis is turned off, all default effects can be suppressed ### Environment ```markdown - OS: - Browser: - Framework: ``` ### Any additional comments? _No response_
