Pattern: Missing rel="noreferrer" for blank anchor tag
Issue: -
For security reasons, anchor tags with target="_blank" should also include rel="noreferrer".
In order to restrict the behavior window.opener access, the original page needs to add a
rel="noopener" attribute to any link that has target="_blank".
However, Firefox does not support that tag, so you should actually use
rel="noopener noreferrer" for full coverage.
By default, the rule considers the use of rel="noreferrer" as
sufficient. The option 'force-rel-redundancy' can be passed to require
rel="noopener noreferrer".
