HTML headers with anchors no longer create links in Table of Contents macro

Since I raised a similar issue in this project, I'm cross-posting this bug report. See TOC-139 for the original.

When adding the example HTML from the macro documentation to a page in an HTML macro, the expected behavior is that the TOC macro will render the heading and create a link the the anchor with a href. Instead, the <a> is created without a href, similar to this Confluence request. I'm not sure if it's an issue with TOC or with the Confluence renderer mentioned in the other JAC issue.

Example HTML:

<h2><a name="pagename-headingname"></a>Heading Name</h2>

Confluence 3.5 renderer would create this HTML for the page:

<a href=​"#pagename-headingname">​Heading Name​</a>​

Confluence 4.2 renderer creates this HTML instead:

<a name=​"pagename-headingname">​Heading Name​</a>​
