Blocked aria-hidden on a <oj-popup> element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden. <oj-popup id="waitPopup" class="wait-popup oj-popup oj-component oj-popup-no-chrome oj-component-initnode oj-complete oj-focus oj-focus-highlight oj-animate-close oj-animate-close-active" tail="none" position.my.horizontal="center" position.my.vertical="center" position.at.horizontal="center" position.at.vertical="center" position.of="window" position.offset.y="-10" modality="modal" draggable="false" auto-dismiss="none" chrome="none" tabindex="-1" style="display: block; top: 279px; left: 842px; transform: scale(0) translateZ(0px); transform-origin: center center; opacity: 0; transition: -webkit-transform 0.4s, opacity 0.4s;" role="tooltip" aria-modal="true" aria-hidden="true">…</oj-popup>Understand this error
