To answer your question, I'll provide the following information:

**Markdown Syntax Support**

The given Markdown text supports several features, including:

1. Footnotes: `[^first]`, `[^second]`
2. Inline footnotes: `^[Text of inline footnote] definition`
3. Definition lists: `Term 1 ~ Definition 1`, `Term 2 ~ Definition 2a`, `Term 2 ~ Definition 2b`
4. Abbreviations: `[HTML]: Hyper Text Markup Language`

**Benchmarking Results**

The latest benchmark results show the performance of three Markdown parsing libraries:

1. **Marked**: 658 executions per second
2. **markdown-it**: 1170 executions per second
3. **Remarkable**: 1285 executions per second

These results suggest that Remarkable is the fastest library among the three, followed by markdown-it, and then Marked.

**Individual Test Cases**

The individual test cases for each library are as follows:

1. **Marked**: `conv.marked.lexer(md)`
2. **markdown-it**: `conv.mdit.parse(md, {})`
3. **Remarkable**: `conv.remarkable.render(md)`

These test cases can be used to further analyze the performance of each library in different scenarios.

Let me know if you'd like me to elaborate on any of these points or provide additional information!
