- Fix parse two markdown document use same
MarkdownPipelineBuilder, one document without[toc]and the other one has, the generated toc block will contains both. This bug is occur case I use theTocOptions.Headingsto store the headings, and don't clear them when all renderer completed, not just clear after toc rendered. - After fixed, markdown document can has more than one
[toc], and all of these can be rendered, though it's useless.
