| Steps to reproduce:
- Create a page in the markdown+github/1.0 syntax with the content ![[Logo|Sandbox.WebHome@XWikiLogo.png]]
- View the page
Expected: the XWikiLogo.png image attached to Sandbox.WebHome is displayed, as it is on a markdown/1.2 page. Actual: a "!" followed by a link to create the page Sandbox.WebHome@XWikiLogo.png is displayed. Cause: the wiki image syntax is enabled with WikiLinkExtension.IMAGE_LINKS in DefaultMarkdownConfiguration only. MarkdownGitHubConfiguration doesn't set it. |
