**Steps to replicate the issue** (include links if applicable):
* Setup a fresh MediaWiki installation.
* Find a page, and open Visual Editor to edit.
* Find the question mark in the toolbar, then click "Read the user guide" inside of it.
**What happens?**:
User is brought to a page named "Mw:Special:MyLanguage/Help:VisualEditor/User_guide" (defined in message "visualeditor-help-link"), which can not be redirected to mediawiki.org in default installations, just return a "Bad title" page.
**What should have happened instead?**:
The link should be redirected to corresponding page on mediawiki.org, insteading showing "Bad title".
**Software version** (on `Special:Version` page; skip for WMF-hosted wikis like Wikipedia): MediaWiki-1.43.0-alpha (e1b6218), VisualEditor (053ef03, lib/ve: f780587)
**Other information** (browser name/version, screenshots, etc.):
When language set to "qqx" while editing using VisualEditor, the buggy link will point to page named "(visualeditor-help-link)", a page name in qqx format.
Although it cannot be redirected to mediawiki.org, when using the content in message "visualeditor-help-link" in a normal link, it can be redirected.
