Steps to reproduce the issue

Create an article in the admin of 4.0b7 ensuring you give a value for Keywords

Link to that article on the frontend, and view the source

Expected result

<meta name=”keywords” content=”bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb” />

Actual result

No keywords tag (note description tag is shown)

System information (as much as possible)

Additional comments

https://help.joomla.org/proxy?keyref=Help40:Articles:_Edit&lang=en states these keywords are "To help Search Engines and other systems classify the content of the Article." which they cannot be helping as they are not rendered
