Missing Markdown support: horizontal rule, emojis

[jackwhelpton]

Environment

• KFP version: 1.0.1

Steps to reproduce

Output a markdown artifact containing the missing features: a horizontal rule, and an emoji, e.g. :warning:

        metadata = {
          "outputs": [
          {
            "storage": "inline",
            "source": "line1\n---\n:warning: Item had multiple genre labels",
            "type": "markdown",
          }]
        }

Expected result

The Visualizations tab and Run output should render the horizontal rule and emoji:

line1

⚠️ Item had multiple genre labels

Instead, the original markup code is visible:

line1 --- :warning: Item had multiple genre labels

---

As a workaround, using the character ⚠️ directly works; this doesn't help with, for example, ℹ️ (:information_source:).

This doesn't help with the horizontal rule, either.

I'm expanding this ticket as I find other missing markdown features: let me know if each one should be spun off as a separate ticket.

Hello @jackwhelpton , feel free to add more missing markdown features in this ticket. We can update the issue description to match the scope as well. Ideally we should use another markdown render which can fit all markdown feature requests.
