BACKGROUND

People who are blind cannot use the visual presentation of a form to determine the label for a form element. In order for screen reader users to be certain of a form field's label, every form input and control needs a label, also known as an "accessible name." When form elements have a programmatically determinable accessible name, a screen reader user can put focus on a form element and the screen reader will automatically read the label and element type together. In addition, some coding methods will create a larger clickable area for the form element which benefits people with motor disabilities.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
