Setting default Markdown extras

First Check

• I added a very descriptive title here.
• I have checked the FAQs for a similar question and didn't find it.
• I used the GitHub search to find a similar question and didn't find it.
• I searched the NiceGUI documentation, with the integrated search.
• I already searched online "How to X in NiceGUI" and didn't find any information.

Example Code

# Wanted
ui.markdown.extras = ["fenced-code-blocks", "tables", "cuddled-lists", "strike"]

# Instead of every time:
ui.markdown(some_text, extras=["fenced-code-blocks", "tables", "cuddled-lists", "strike"])

Description

Some LLM models sometime forget to add a separator line between a bulleted list.
The markdown extension cuddle-lists solves this.
But adding it to the extras each time ui.markdown is used is tedious (and error prone)

Hi @tomsquest,

I agree that a static list of default extras would be useful. Let's convert this discussion into a feature request!

The implementation shouldn't be too hard. But I think we should wait for a solution to #4857 where we're currently thinking about signatures with default values.

As a workaround, you could derive a custom Markdown element:

class CuddlyMarkdown(Markdown):
    def __init__(self, content: str = '') -> None:
        super().__init__(content, extras=['fenced-code-blocks', 'tables', 'cuddled-lists'])

Thanks @falkoschindler for the answer.
I like your solution of a custom element.
