reactjs - React Material UI - 为什么 CSS 类在使用 withStyles 时会重复？

Question

CSS 类在执行时不断重复，有什么特别的原因吗？

<Grid
      item
      xs={12}
      md={12}
      className={classes.subFilterWrapper}
      data-locator={locators.COMPONENT_SUBFILTERWRAPPER}
    >
    </Grid>

上面的代码导致

<div class="MuiGrid-root MuiGrid-root makeStyles-subFilterWrapper-4108 MuiGrid-item MuiGrid-item MuiGrid-grid-xs-12 MuiGrid-grid-xs-12 MuiGrid-grid-md-12 MuiGrid-grid-md-12" data-locator="ProductCardList-SubFilterWrapper"></div>
