Current behavior

Code block in MarkdownTextBlock is merging with above line if it doesn't have a new line above it.

Expected behavior

Code block should be displayed in new line even though it doesn't have a new line above it.

Minimal reproduction of the problem with instructions

UWPCommunityToolkit
```XAML
<Grid/>
```

Use the above markdown in MarkdownTextBlock

The only reason why this works in GitHub, is because GitHub's renderer is more lenient, it isn't proper Markdown.

[Vijay-Nirmal]

We can't expect "proper Markdown" from users. We should be flexible as GitHub.

Hey! What is the current status of this issue?

I think it would be useful to implement this, specifically because GitHub supports it. If I want to render the readme.md for a project within my app, for example.
