Is it against accessibility if there is no cancel button(e.g. X) in a dialog without cancel function as in the example above? The only way to return to the previous step is to use 'Back button' after switching screens.
In a practical case, the two buttons on the bottom ('No, Thaks' and 'Payment') are the means to move on to the next step in the dialog below. In this case, the only way the user can cancel is by using the ESC key. In this case, is it against accessibility because it cannot be reversed?
