Compressor plugin not called when using addFiles programmatically

[recyclerobot]

Initial checklist

• I understand this is a bug report and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Steps to reproduce

define a new uppy with compressor plugin:

new Uppy({
  autoProceed: true
})
  .use(Compressor, { convertSize: Infinity })
  .use(ImageEditor)
  .use(Tus, {
    endpoint: "/api/upload"
  })

call uppy.addFile

const generatedId = uppy.addFile({
  id: v4(),
  data: blob,
  name: filename ?? "clipboard-image.png",
  type: type ?? "image/png",
  meta: {
    ourInternalId: 'xxx'
  }
});

Expected behavior

compress the image and upload

Actual behavior

uncompressed image is uploaded.

Using the dashboard, the image does get compressed, only when calling uppy programmatically it won't compress
