Subtle changes, bugs and feedback

Quotes copy the text and not HTML fragments.

It has always been the case that neither vBulletin BBCode nor the Markdown engine we use knows how to balance HTML (ensure all opening tags have closing tags, and that all closing tags have opening tags), and whilst vBulletin would copy the whole post it was possible to create BBCode that broke a web page.

With Markdown, and the ability to copy a fragment of a comment, this is far more likely to happen.

So until the Markdown engine or post-processor supports AST (abstract syntax tree, the foundation for a balanced HTML tree), or Microcosm supports "whole comment quoting" (it won't be possible to only quote a portion of a comment and ensure a balanced tree) the quoting is limited to copying the text (and not the HTML) that you have highlighted.
