When.setFocus() is used to explicitly give focus to a given element. That element must have the when-focus class, or it will throw an error.

<div id="div1"></div>
<div id="div2" class="when-focus"></div>

const div1 = document.getElementById('div1');
const div2 = document.getElementById('div2');

// throws error
When.setFocus(div1);

// succeeds
When.setFocus(div2);
