为什么在 Material-UI 中单击 TextField 时，AccordionSummary 背景会变为灰色？

Question

我正在使用 Material-UI 的 Accordion 并且在 AccordionSummary 里面我有一个 <TextField /> （实际上是由 Formik 和 formik 控制的-material-ui) 和 AccordionSummary 的背景仅在单击字段内部时变为灰色。我不希望它这样做，而且它似乎不是手风琴 API 配置的任何东西，除非我遗漏了什么。我怎样才能阻止它以这种方式运行？

我在 Codesandbox 上重现了这个问题。

这是来自沙盒的完整代码：

import React from "react";
import { Formik, Field, Form, ErrorMessage } from "formik";
import { TextField, CheckboxWithLabel, Select } from "formik-material-ui";

import AccordionDetails from "@material-ui/core/AccordionDetails";
import AccordionSummary from "@material-ui/core/AccordionSummary";

export default function App() {
  return (

您看到的也是 focused styling for AccordionSummary. You can observe this in the Accordion demos，方法是单击手风琴，然后使用 Tab 键移动到下一个 AccordionSummary。这是出于可访问性的原因，以便用户在使用键盘导航时可以知道焦点在手风琴中的位置。

您可以使用以下内容覆盖它：

import MuiAccordionSummary from "@material-ui/core/AccordionSummary";
import { withStyles } from "@material-ui/core/styles";

const AccordionSummary = withStyles({
  root: {
    "&.Mui-focused": {
      backgroundColor: "inherit"
    }
  }
})(MuiAccordionSummary);

为什么在 Material-UI 中单击 TextField 时，AccordionSummary 背景会变为灰色？
