There is a difference in the user experience between users employing a screen reader (specifically JAWS) and those not using one while interacting with the MapML solution. The discrepancy pertains to the number of restaurant information buttons that can be expanded simultaneously.
For users employing the JAWS screen reader, they are able to open multiple restaurant information buttons all at once. However, users who are not using a screen reader are restricted to opening only one restaurant information button at a time.
