The feedback tool for VisualEditor needs to direct editors to a centralized location, for some wikis, per T92661: Plan to redirect inactive VisualEditor feedback pages for some wikis to mediawiki.org.
Therefore, it needs to be possible to set an interwiki link as the destination. The destination is set via [[mediawiki:Visualeditor-feedback-link]]
This does not currently work.
E.g. The link at testwiki is set to direct feedback to mediawiki.org's VE feedback pages, mw:VisualEditor/Feedback (as desired)
https://test.wikipedia.org/wiki/MediaWiki:Visualeditor-feedback-link
but when I submit feedback using the tool
https://test.wikipedia.org/wiki/User:Quiddity/sandbox?veaction=edit
I get an error message:
webconsole:
Feedback report failed because MessagePoster could not be fetched load.php:156:550
This is followup work to T91805: T7. Flow support for the mediawiki.feedback form
