markdown links within a document don't render properly, because they incorrectly include a query string

I have a Markdown document with relative links:

    # <a name='foo'>section foo</a> #
    lorem ipsum foo foo foo 

    ...

    See the [foo](#foo) section for more information.

The #foo relative link doesn't work properly. The renderer for -Stash-Bitbucket Server adds a copy of the query string to it, so instead of getting this as a result in HTML:

    See the <a href="#foo">foo</a> section for more information.

if I am browsing another branch rather than the master, I get this (fragment first, then query string):

    See the <a href="#foo?at=refs%2Fheads%2Ffeature%foodoc">foo</a> section for more information.

This is wrong. Fragments should be the last thing in a URL, and specifying a query string isn't necessary if it's a fragment-only reference.
