Internal links not working

[petered]

First of all, thanks for making this vary handy tool. I'm using it to create a user manual for my App, and finding it would be very useful to have a table of contents at the top, but I'm not able to create one because the internal linking doesn't work.

Subject of the issue

Internal links, e.g.

[Link to Section](#section-name)

...

# Section Name

Steps to reproduce

Above markdown should do it.

Expected behaviour

Upon clicking internal link, screen should jump to that heading.

Actual behaviour

Screen just goes blank.
