#18 External Video Links (YouTube) Breaking the Topic Frame

[Dan van Zyl]

Problem
If a KnowledgeDesk topic contained a standard link to a YouTube video, the topicFrame would attempt to load YouTube directly. Because YouTube enforces strict X-Frame-Options: sameorigin security headers, the frame displayed a "www.youtube.com refused to connect" error, and the browser console filled with SecurityError messages. Users had to click "Back" to return to the documentation.

Fix
interceptIframeLinks() in viewer.js now explicitly catches any link containing youtube.com or youtu.be. It prevents the frame navigation entirely and forces the link to open in a new browser tab via window.open().

Effect
The KnowledgeDesk topic remains visible and stable. Clicking a video link instantly opens a new tab for the video, with zero console errors and no need to use the browser's "Back" button.
