MUI v5 + Storybook：主题和字体系列在 Storybook 中不起作用答案

【问题描述】：

我遇到了一个问题，即 MUI 主题在代码沙盒中有效，但在故事书中无效

演示它在没有故事书的情况下工作： https://codesandbox.io/s/typescript-material-ui-textfield-ojk3h?file=/src/App.tsx

演示表明它与故事书一起打破 Git 仓库：https://github.com/EdmundMai/mui-v5-storybook

这是我的组件：

import React from "react";
import styled from "styled-components";
import { createTheme, ThemeProvider } from "@mui/material/styles";
import MuiTextField from "@mui/material/TextField";

const StyledTextField = styled(MuiTextField)`
  width: 288px;
`;

const theme = createTheme({
  typography: {
    allVariants: {
      fontFamily: "serif",
      fontSize: "12px",
    },
  },
});

const ThemeProviderMine = () => (
  <ThemeProvider theme={theme}>
    <StyledTextField placeholder="Foobar" label={"Select a foobar"} />
  </ThemeProvider>
);

export default ThemeProviderMine;

如您所见，在代码沙盒上一切正常。我的自定义字体和字体大小都使用了：

但是，当我使用故事书时，我的自定义字体和字体大小会被忽略：

有人知道为什么会这样吗？
