Newlines without > break callouts (Obsidian inconsistency)

[MaxWolf-01]

Describe the bug

In Obsidian, both of the below ways of defining a callout with multiple lines work, not in quartz:

> [!note]
Line
Anotherone

> [!note]
>Line
>Anotherone

Expected behavior

The callout should only stop after an empty newline, not requiring > on every line.
The same goes for nested callouts:

> [!note] Outer 
Outer
> > [!note] Inner 
> > Inner
>Inner 
>
>Outer

It would be nice to have a core plugin to enable this Obsidian markdown feature, even if it is not markdown standard, as with other features.

Desktop (please complete the following information):

• Quartz Version: v4@latest
• node Version: v22.11.0
• npm version: 10.9.0
• OS: Ubuntu 22.04
• Browser Firefox

Additional context

The following transformer fixes it (not extensively tested yet):

import { QuartzTransformerPlugin } from "../types"

export const CalloutNewlineFix: QuartzTransformerPlugin = () => {
  return {
    name: "CalloutNewlineFix",
    textTransform(_ctx, src) {
      if (typeof src !== "string") {
        src = src.toString()
      }

      return src.replace(
        /^> \[!(\w+)]\s*\n((?:[^>\n][^\n]*\n?)+)/gm,
        (_match: string, type: string, content: string) => {
          const fixedContent = content
            .trim()
            .split("\n")
            .map((line) => `>${line}`)
            .join("\n")

          return `> [!${type}]\n${fixedContent}`
        },
      )
    }
  }
}
