MaterialUI TextField not resizing properly when pasting delimited list of emails

Question

I have a form to create users, and the user can paste a delimited list of email addresses into a TextField, where they are turned into Chips.

const MultiUserAdd = () => {
  const [emails, setEmails] = useState<string[]>([]);

  const handleEmailChange = (newEmails: string[]) => {
    setEmails(newEmails);
    console.log(emails);
  };

  const handlePaste = (event: React.ClipboardEvent<HTMLDivElement>) => {
    const clipboardData = event.clipboardData?.getData('text/plain');
    if (clipboardData) {
      const cleanedEmails = clipboardData
        .replace(/[\s,]+/g, ' ')
        .trim()
        .split(' ')
        .filter((email) => email.includes('@'));
      handleEmailChange([...emails, ...cleanedEmails]);
    }
    event.preventDefault();
  };

  const handleDelete = (index: number) => {
    const newEmails = [...emails];
    newEmails.splice(index, 1);
    handleEmailChange(newEmails);
  };

  const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    const newEmails = event.target.value.split(',');
    handleEmailChange(newEmails);
  };

  return (
    <>
    <Box
    component="form"
    onSubmit={onSubmit}
    >
    <Typography id="modal-modal-title" variant="h4" component="h4">
        Bulk Add Users via Email
    </Typography>
    <FormControl>
    <TextField
      variant="outlined"
      fullWidth
      multiline
      placeholder="Enter or paste email addresses"
      onPaste={handlePaste}
      value={emails.join(',')}
      onChange={handleChange}
      InputProps={{
        startAdornment: emails.map((email, index) => (
          <Chip key={index} label={email} onDelete={() => handleDelete(index)} />
        )),
        inputProps: {
          style: {
            display: 'flex',
            flexWrap: 'wrap'
          }
        }
      }}
    />
    </FormControl>
    </Box>
    </>
  );
};

However, once the list is pasted, the chips just continue outside of the TextField. I tried adding the multiline prop, but it does not solve the chip issue. I am thinking that there is something incorrect with my paste function, but I cannot seem to see it.
