test code

I tried to download canvas to image:

const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

ctx.fillStyle = 'green';
ctx.fillRect(10, 10, 150, 100);

canvas.toBlob(function (blob) {
  const link = document.createElement('a');
  link.download = 'example.png';
  link.href = URL.createObjectURL(blob);
  link.click();
  URL.revokeObjectURL(link.href);
}, 'image/png');

Everything is ok for following device and safari version:
- macOS Ventura 13.0.1 Safari 16.1
- iPhone 14 Plus iOS 16.3
- iPhone 14（Simulator) iOS 16.4

However, on iPhone 13（Simulator）iOS 16.2, the image can be downloaded, but the web inspector gets following error:

Failed to load resource: Frame load interrupted
