Selected device hides nearby markers when clustering is enabled

Hi everyone,

I noticed an issue on the main map with marker clustering.

If I select a device and then zoom out, nearby devices disappear when they reach the zoom level where they should be grouped into a cluster.

If I deselect the device, the missing devices and cluster appear again.

I also tested with marker clustering disabled. In that case, I can select a device and zoom out normally and the other devices remain visible.

So the issue only seems to happen when a device is selected and marker clustering is enabled.

I attached two screenshots showing the behavior.

Thanks.

This should fix the problem:
