What

• The contribution tag in the navigation bar does not get highlighted even when on the page which has a contribution panel .

Steps to reproduce the behavior

1. Go to any product page on the website ( here's one http://world.openfoodfacts.localhost/product/3451790834080/uht-sterilised-semi-skimmed-milk-enriched-with-vitamins-b1-b2-b5-b12-and-d-long-life-elle-vire )
2. Move downward to the contributions panel
3. You will see that the contribution panel even though being there, the contribution tag does not get highlighted

Expected behavior

• The contribution tag should get highlighted like the rest of the tags in the navigation bar do
