Operating system

Steps to reproduce this

Steps:

1. Create a File representing a video or audio file.
2. Pass the file to p5.File._load(), which creates an object URL and exposes it through file.data.
3. Pass file.data to createImg(), then call img.remove(). Observe that URL.revokeObjectURL() is never called for the object URL created by _load().

Snippet:

test('does not revoke the object URL when the created image is removed', async () => {
  const blob = new Blob(['fake video'], { type: 'video/mp4' });
  const inputFile = new window.File([blob], 'test.mp4', {
    type: 'video/mp4'
  });

  const objectURL = 'blob:test-url';

  vi.spyOn(URL, 'createObjectURL').mockReturnValue(objectURL);
  const revokeObjectURL = vi.spyOn(URL, 'revokeObjectURL');

  let file;

  File._load(inputFile, loadedFile => {
    file = loadedFile;
  });

  const img = mockP5Prototype.createImg(file.data, '');
  img.remove();

  expect(revokeObjectURL).not.toHaveBeenCalled();
});
