Incorrect symbol when converting markdown to typst

[ninpnin]

When converting markdown to typst, the binomial symbol is turned into a division. So

${n\choose k}$

is turned into a division with parenthesis

$lr((n / k))$

while it should be

$binom(n,k)$

i.e. the binomial expression

The command to run is

pandoc binom-test.md -o binom-test.typ -t typst

The same thing happens on pandoc 3.1.6.2 and in the online interface.

texmath parses this as

[ EDelimited
    "("
    ")"
    [ Right (EFraction NoLineFrac (EIdentifier "n") (EIdentifier "k"))
    ]
]

but the NoLineFrac is ignored by the typst writer, apparently.
