LayoutShiftAttribution.currentRect

A DOMRectReadOnly object.

The following example prints the currentRect of the first item in LayoutShift.sources to the console.

new PerformanceObserver((list) => {
  for (const {sources} of list.getEntries()) {
    if (sources) {
      console.log(sources[0].currentRect);
    }
  }
}).observe({type: 'layout-shift', buffered: true});
