**List of steps to reproduce** (step by step, including full links if applicable):
* Navigate to https://de.wikivoyage.org/wiki/Berlin/Mitte
* Hover “+”-symbol in the mapframe
**What happens?**:
When hovering the “+”-button the CSS-rule of ext.kartographer.style
```
.mw-kartographer-interactive .leaflet-draw-actions a, .mw-kartographer-interactive .leaflet-bar > a {
border-bottom-width: 0;
}
```
is overridden by
```
.leaflet-bar a, .leaflet-bar a:hover {
border-bottom: 1px solid #ddd;
}
```
which leads to all buttons below the “+”-button being pushed down one pixel.
**What should have happened instead?**:
No button shoving shall occur.
**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.**:
