Reproduction

1. Open the playground: https://comark.dev/play/editor?example=all-features
2. Clear the editor and paste the markdown below
3. Observe the rendered output — a stray * appears at the end

Input to paste:

*   **Preheat the oven:** Set the temperature to 200 degrees.

Description

When a list item's content ends with bold text (**text**) immediately followed by a colon-separated sentence ending in a period, comark appends an extra * character right after the closing punctuation.

Input

​```md

• Preheat the oven: Set the temperature to 200 degrees.
  ​```

Expected output

Preheat the oven: Set the temperature to 200 degrees.

Actual output

Preheat the oven: Set the temperature to 200 degrees.*

This is a minimal reproduction — a single list item with bold text at the start followed by plain text ending in a period is enough to trigger the bug. It is not specific to:

• list length or position within a list
• non-ASCII characters (reproduced with plain English/ASCII text)

It looks like an emphasis-marker parsing issue triggered when bold text is followed by additional text ending in a period at the end of a line/item.

@farnabaz your text ends with a line break \n, while mine ends with a list item
