Steps to reproduce:

0. Start the server
1. Add a Wiki portlet to a page
2. Edit the front page
3. Add the following:

<<TableOfContents>> - this has to be at the top
A heading ("heading1" and set it as Heading 1 from the list)
A subheading ("subheading" and set it as Heading 3 from the list)
A wall of text
A heading ("heading2" and set it as Heading 1 from the list)
A subheading ("subheading" and set it as Heading 3 from the list)
A wall of text

4. Publish
5. Click the second subheading

Actual results:
This takes you to the 1st subheading's wall of text. No matter which subheading you click, you will be taken to view the 1st subheading's wall of text.
Expected results:
Clicking on a subheading should take you to that subheading's text.
