Describe the bug

According to the Slidev documentation:

Slidev supports optional Comark Syntax (formerly known as MDC, Markdown Components) powered by @comark/markdown-it.

In the Comark documentation, blocks can be styled by adding a space at the end, and then curly braces.

In Slidev, this does not style the block, but rather the last attribute.

Minimal reproduction

---
comark: true
---

## h2 with _italic_ {style="color: blue"}

The whole line should be blue, not just the italic text.

Steps to reproduce the behavior:

1. Expected behaviour (comark):
   1. Open https://comark.dev/play/editor?example=undefined
   2. Paste the code block above
   3. Observe that the entire line is blue.
2. Slidev behaviour:
   1. Open https://sli.dev/new
   2. Paste the code block above
   3. Observe that only the italic text is blue.
   4. There is no way to style the entire line.

Further notes

Additionally, wrapping a list, table, blockquote, or code block does not work
