The problem when putting the jump link before the heading is that on pages that have a 2nd degree heading at the top, will also have jump link which does not make much sense. An example is the layout.md page in the current MDwiki Wiki:

I've thrown out the 2 commits that did nothing because reverted themself, and squashed merged the other to fixes into single commit 5ba2bc5

Thanks for the fixes!

P.S: You might want to enable trailing whitespace highlighting in your editor, as there were empty lines with whitespace in your pull request ;)
