FW: [w3c/wcag] 1.4.11 if a button has a background less than 3:1 and no border does it pass (#800)

Low vision folks – some changes evidently were made to the understanding document of 1.4.11 indicating that sufficient contrast for identifying elements was not needed when text was present such as with button as text is enough to indicate that something is interactive even when low contrast is used.   This seems to significantly carve out 1.4.11 in relation to UI controls as most controls like page tabs, input fields with placeholders all have text.

At the bottom of the email is a link to the github issue if people want to comment (or comment another way as needed).

Boundaries
This success criteria does not require that controls have a visual boundary indicating the hit area, but if the visual indicator of the control is the only way to identify the control, then that indicator must have sufficient contrast. If text (or an icon) within a button or placeholder text inside a text input is visible and there is no visual indication of the hit area then the Success Criterion is passed. If a button with text also has a colored border, since the border does not provide the only indication there is no contrast requirement beyond the text contrast (1.4.3 Contrast (Minimum)). Note that for people with cognitive disabilities it is recommended to delineate the boundary of controls to aid in the recognition of controls and therefore the completion of activities.
