Understandable / 3.2 Predictable
3.2.1On Focus
Level ASimply moving focus to an element -- a form field, a button -- must not by itself trigger a change of context such as page navigation, a modal opening, or an automatic form submission. Keyboard and screen reader users tab through elements sequentially, so an unexpected change on focus alone easily disorients them.
