`table-striped` is invisible in `darkly` HTML theme

Bug description

Perhaps I was expecting too much, and have verified it works in the default theme. I am using darkly and the striped visually appears to have no effect.

Steps to reproduce

_quarto.yml

---
project:
  type: website

format:
  html:
    theme: darkly

index.qmd

---
format: html
listing:
  contents: .
  table-striped: true
  type: table
---

a.qmd

---
title: A
format: html
---

b.qmd

---
title: B
format: html
---

Expected behavior

I would expect alternating black and some shade of grey perhaps?

Actual behavior

All rows appear essentially the same - works in default theme
