When using Leaflet, if a popup is overlaying a polygon, it can block the mouseover event from reaching the polygon. This can happen when the popup is opened on top of the polygon, and the popup's DOM elements prevent the mouseover event from reaching the underlying polygon.

To address this issue and allow the mouseover event to reach the polygon even when a popup is open, you can use the following approach:

  1. Close Popup on Mouseover: When the user hovers over the polygon, close the open popup programmatically. This will allow the mouseover event to reach the polygon. You can do this by using the closePopup method on the Leaflet map instance.

    Here's an example:

    javascript
    const polygon = L.polygon([...coordinates]).addTo(map); polygon.on('mouseover', () => { // Close the open popup if it exists if (map._popup) { map.closePopup(); } // Add your mouseover event handling logic here });
  2. Open Popup on Mouseout: If you want the popup to reappear when the user moves the mouse away from the polygon, you can open the popup again when the user moves the mouse out of the polygon.

    Here's an example:

    javascript
    polygon.on('mouseout', () => { // Open the popup when the mouse moves out of the polygon polygon.bindPopup('Popup content').openPopup(); // Add your mouseout event handling logic here });

By using these event listeners, you can close the popup when the user hovers over the polygon to allow the mouseover event to work correctly, and then open the popup again when the user moves the mouse out of the polygon.

Keep in mind that this solution assumes you are using the Leaflet library to work with maps and polygons. If you are using a different library or tool, the approach might be different. Additionally, make sure to handle other events and interactions as needed for your specific use case.
