**List of steps to reproduce** (step by step, including full links if applicable):
* Visit pl or dewiki
* Article with coordantes e.g.: https://pl.wikipedia.org/wiki/Ob%C3%B3z_jeniecki_w_Sandakanie
* Open map on top of the article (pl: "mapa").
* Zoom out (wheel).
**What happens?**:
Whole page is scrolled down.
**What should have happened instead?**:
Only the map should change (zoom).
**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc**:
If you could patch OL 2.12 then this should work. The file is currently located here:
https://tools.wmflabs.org/osm/libs/openlayers/2.12/OpenLayers.js
Patched version attached (essentially I used VSC to beatify and just changed `OpenLayers.Handler.MouseWheel` to add event options `{passive: false}`)

Tested on Firefox and Chrome. The changed would work in IE too, but the map is not loaded in IE (at least not on plwiki).
PS: I've checked and the scrolling problem doesn't occur in latest OpenLayers library. But seems like upgrade would require quite a lot of changes in WIWOSM, maybe a re-write even.
