“Member name or ID” field appears to be mislabeled
The label “Member name or ID” is associated through ID to an input field with an ID of “add-block-input.” The ID of the input field is “groupAddMemberComboID.” There is another input field but does not match the label ID either. As a result the screenreader user receives no helpful feedback when they tab or move to the input field.
Change the associated ID (i.e. for = “ID”) in the label statement shown above to match the ID of the input field: “groupAddMemberComboID”
