Wrong upright style and spacing for vecrow() and Greek letters

[CarrotDLaw]

When the first element in vecrow() is a Greek letter, there are unexpected spacing and upright style issues, like the first three lines in the following. The last three lines are how the output is supposed to be.

I found a temporary solution that is to use italic(alpha) instead of just alpha in the first element, though.

$
& vecrow(alpha, beta) \
& vecrow(alpha, italic(beta)) \
& vecrow(alpha, b) \
& vecrow(a, beta) \
& vecrow(italic(alpha), beta) \
& (alpha, beta) \
$

Some investigation:

https://github.com/Leedehai/typst-physics/blob/94c89824cbb69d1513e49ea7ea3d0bd90f7016fd/physica.typ#L152

#grid(columns: (1fr, 1fr), [
  ```typst $lr((alpha, beta/gamma))$```

  $lr((alpha, beta/gamma))$

  #repr($lr((alpha, beta/gamma))$)
], [
  ```typst $vecrow(alpha, beta/gamma)$```

  $vecrow(alpha, beta/gamma)$

  #repr($vecrow(alpha, beta/gamma)$)
])

Possible fix

• Change "," to [,]

  #let vecrow(..content) = $lr(( #content.pos().join([,]) ))$

  

• Directly use math.lr

  #let vecrow(..content) = math.lr([(] + content.pos().join([,]) + [)])

  It imitates $lr(…)$ better, but longer…

Wow, thanks! Let me see..
