Also, the change in insert-hyperlink (from `this.linkUrl.indexOf("http") === -1` to `!this.linkUrl.startsWith("http")`) was intentional fix: we don't want to prevent users from looking up topics with http in their titles.
This commit adds a new property "discourseReferrerPolicy" to the
set of supported configuration properties for the comment embed
script. If provided the value will be used to set the "referrerPolicy"
attribute on the iframe created to display the comments. This in turn
will allow embedding pages to define a more lenient referer policy on
the embed iframe for pages whose default policy is so strict it
keeps the comment embed from working.
Example:
* Setup:
* Discourse hosted at discourse.example.com
* Comments embedded at example.com
* Referrer-Policy at example.com set to 'same-origin'
* Without this commit:
* Loading the comments fails due to the referer being empty
* With this commit and no adjusted configuration:
* Loading the comments fails due to the referer being empty
(= same behaviour as without the commit)
* With this commit and DiscourseEmbed.discourseReferrerPolicy =
'no-referrer-when-downgrade' as additional configuration:
* Loading the comments succeeds
Note that this change is of special interest for embedding pages
wanting to restrict data flows under the terms of the GDPR since
it allows selectively whitelisting comment embeds while preventing
referer leaking by default.
Feature to allow each imported post to be created using a different discourse
username. A possible use case of this is a multi-author blog where discourse
is being used to track comments. This feature allows authors to receive
updates when someone leaves a comment on one of their articles because each of
the imported posts can be created using the discourse username of the author.
