Description

• For clusters the circles are vocalized white circle,
• The number that is placed in the middle of the cluster should not be vocalized either

Fix

aria-hidden=true to prevent vocalization to the screen reader

The number that is placed in the middle of the cluster should not be vocalized either

In that case there'd be nothing to announce to screen readers when a marker cluster is focused. I do think however, that the marker cluster's accessible name can be improved (to convey to AT users what the numbers mean): https://github.com/Leaflet/Leaflet.markercluster/issues/1006

Hello, in IOT-Map-Component the clusters have an information popup which is read by the screen reader.

There is therefore a redundancy of information

In the image above, we see that the cluster number is vocalized twice.

In addition it is vocalized at the very end without us knowing what it is
