{longdiv} is not working sometimes.

[Satosh-J]

let tex = '12\\enclose{longdiv}{48}'
  return (
    <Box sx={{ minWidth: 200, fontSize: 30, color: 'white' }}>
      <MathJax.Provider>
        <MathJax.Node
          formula={he.decode(tex)}
        />
      </MathJax.Provider>
    </Box>
  );

this displays incorrectly.
