I created a custom <Tab/> and I want to control its selection color by using the following code:

Sandbox Demo Code

export const Tab = styled(MuiTab)({
  "&.Mui-selected": {
    color: "red"
  }
});

However, I found:

1. Directly apply custom style components => The selected color is red

2.Wrapping custom style componentsin a self-created component => does not work, not even the default selected color

<Tabs value={value} variant="scrollable">
  <Tab label="Tab" value={1} /> //选中颜色 = 默认值
  <TestTab label="TestTab" value={2} /> //选中颜色 = 默认值（问题在这里）
  <Styled.Tab label="Styled.Tab" value={3} /> //选中颜色 = 红色（好的，但我想包装在自创建的组件中）
</Tabs>

Is this normal behavior that MUI does not recognize self-created Tabs?
