Nature article matched DOI by page text not expected meta tag

In http://api.eventdata.crossref.org/v1/events/13d9d491-65f5-4278-bb64-7daf16b6c9e9

The match was made with 'landing-page-text' and 'checked-url-basic'. This is fine, but it could have matched in preference with the meta tag. Looking at the source of https://www.nature.com/articles/s41586-018-0007-4 the DOI is included:

<meta name="dc.identifier" content="doi:10.1038/s41586-018-0007-4"/>
<meta name="DOI" content="10.1038/s41586-018-0007-4"/>
<meta name="citation_doi" content="10.1038/s41586-018-0007-4"/>
