Unable to pass @id to IIIF layout

[edsilv]

I'm using v0.27.2

When callng .tile passing the iiif layout, the resulting info.json does not have the correct @id.

sharp(image)
    .tile({
      layout: "iiif",
      id: "https://test.com"
    })
    .toFile(directory, (err, _info) => {
      resolve();
    }); 

This should result in:

{
  "@context": "http://iiif.io/api/image/2/context.json",
  "@id": "https://test.com/directory",

But it still uses the default example.com id:

{
  "@context": "http://iiif.io/api/image/2/context.json",
  "@id": "https://example.com/directory",

Ostensibly, the passed id should be used here in libvips: https://github.com/libvips/libvips/blob/master/libvips/foreign/dzsave.c#L1006

The id option appears to be missing here: https://github.com/lovell/sharp/blob/master/lib/output.js#L713

However, when I add:

    if (is.defined(options.id)) {
      if (is.string(options.id)) {
        this.options.id = options.id;
      } else {
        throw is.invalidParameterError('id', 'not a string', options.id);
      }
    }

in my local copy of Sharp, it's not making any difference to the outputted info.json...

What is the output of running npx envinfo --binaries --system?
