When I add a `&::placement` style to a MUI TextField I get this error: ``` TypeError Cannot read properties of undefined (reading 'push') ``` You can see an example of the code here to reproduce this error: https://codesandbox.io/p/sandbox/runtime-cache-v573zp?file=%2Fsrc%2FDemo.tsx%3A16%2C30 The expected result is that the TextField's placeholder text should be colored magenta in the above example.
