Popup don't open manually if 2 marks have the exact coordinates

[WagdySamih]

• I've searched through the issues to make sure it's not yet reported

---

• Leaflet version: 4.2.1
• Leaflet.MarkerCluster version: 2.1.0
• Browser (with version): Chrome - 117
• OS/Platform: Ubuntu 20.04

How to reproduce

Try to have marks with the exact position same lat and long
Try to open the popup from any outside source for the same duplicated position popup

What behavior I'm expecting and which behavior I'm seeing

The popup doesn't open
Note:
The code below works totally fine if there is no clustering

 <MarkerClusterGroup
        iconCreateFunction={createClusterCustomIcon}
        maxClusterRadius={30}
        spiderfyOnMaxZoom
        polygonOptions={{
          fillColor: '#ffffff',
          color: '#7DD68E',
          weight: 5,
          opacity: 1.0,
          fillOpacity: 0.8,
        }}
        showCoverageOnHover={true}
      >
        {markers.map((marker, index) => (
          <Marker
            position={marker.coordinates}
            key={index}
            ref={myRefs.current[index]}
            icon={greenIcon(marker?.markerImage || '')}
            eventHandlers={{
              click: () => {
                setLocalSelectedLocation({
                  position: marker.coordinates,
                  user: marker.user,
                });
              },
            }}
          >
            <Popup
              key={index}
              className={styles.popup_container}
              offset={[10, 5]}
            >
              {localSelectedLocation && (
                <div> any thing </div>
              )}
            </Popup>
          </Marker>
        ))}
 </MarkerClusterGroup>

Hello, I have the same problem. Have you solved it in some way?

Update: I had this problem because the Popup was used like a tooltip (showing the popup and setting a state on a onMouseOver). I changed it to a real Tooltip component and now I can click on the "spiderfied" marker without issue.
