Issue Summary

In the Trello single-board Map view, clicking a map location marker can cause it to disappear and require a full-page reload to restore the markers.

Steps to Reproduce

1. Open a Trello board that contains multiple cards with location data 

1. Open the Map View.

1. Click on a specific location marker/flag to view card details.

1. Click on a different location marker elsewhere on the map.

Expected Results

The map should remain stable, allowing the user to click between different markers to view card details without any elements being removed from the UI.

Actual Results

The previously clicked marker (and occasionally the current one) vanishes from the map interface. The markers remain missing until the browser page is manually reloaded.

• Reproduced in: Microsoft Edge and Firefox (both latest versions).

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available. Users must reload the page to restore visibility of the markers.
