我这里你的例子是正常的。同样是5.5.1。请确认你的浏览器是否支持backdrop-filter

我这边得出的表现是这样的（使用 backdrop-filter: blur()） echarts 在线编辑器：chrome 正常，firefox 异常 vite + react 空白工程：chrome、firefox 都正常 vite + react 成品工程：chrome、firefox 都异常（可能是因为 echarts 层级过深导致的？）

最终是通过 appendTo 解决的 https://echarts.apache.org/zh/option.html#tooltip.appendTo
