Expected Results

The tooltip which appears on mouse hovers on "user name" link should also be available for screen reader users. For this the element that serves as the tooltip container should have role="tooltip". The element that triggers the tooltip references the tooltip element with aria-described by. In addition the content of tooltip should be read by screen reader.
