Actual behaviour The unnecessary messages are being announced

Expected behaviour The unnecessary messages should be hidden with aria-hidden so it could still be announced when the actual use case is being triggered

More information When user is navigating with Virtual cursor, there is a hidden message on top of the grid that is being announced by the SR. The message is announced because SR thinks that this message is part of the screen. This message is hidden on top of the grid. E.g. "No rows to show" when the page is loaded. The message could change based on the action done by the user, e.g. user has already navigated to the header of the column which announces "Press enter to sort the column or navigate to unselected row then there will be an announcement like "Press space to select the row", these 2 announcements/messages then will replace that "unnecessary message" on top of the grid. So if you navigate back to the top of the grid WITH VIRTUAL CURSOR, you can here those messages being announced.
