Leaflet - openPopup()

Question

I just want to ask if there is some possibility of determining where the popup appears. In my case, when I mouseOver on some country on the map, some of the popup windows appear in a nonsensical position.

I have an onEachCountry function where I define a popupContent and also create a popup. And in my mouseOver function I openPopup. Popup is connected with geojson file with Country names. So for example when i mouseover on France the popup will appear on little Island of France in Indian ocean and I want it on France.

function mouseOver(e) {
  let layer = e.target;
  layer.openPopup();
  let ishiglightedlayer = layer.options.weight === 2;
  if (ishiglightedlayer) {
    layer.setStyle({ fillOpacity: 0.5 });
  } else {
    layer.setStyle({ fillColor: "#78dfff" });
  }
}

function onEachCountry(country, layer) {
  const countryName = country.properties.ADMIN;
  layer.bindPopup(countryName);
  // events
  layer.on({
    mouseover: mouseOver,
    mouseout: mouseOut,
    click: selectLayer,
  });
}
