This behaviour is missing the last part of setting the data for entries from the uploader. At the moment we only have the
entry.progress(100)
To say that an upload is finished, without the ability to update entry meta.
What would be amazing is something like:
const meta = {url: result.url}
entry.finish(meta)
As now from what i understand we need to add a hidden input element and add meta-data there?
