Zoom-out a yellow box with mouse scroll and then pan the box. Watch the result.
note: happens when div is reasonably big.
function createLargeBlock() {
layer.innerHTML = '<div style="width: 6400px; height: 3600px;" class="large-block"></div>';
}
note2: in a few previous major versions this worked well.
