Disable inline Youtube previews
When content is not entered via the Canvas Rich Content Editor, Canvas will automatically embed a video preview whenever it sees a link to a YouTube video (and perhaps other video services). This can break the design intent. e.g. this problem and solution from the Canvas Community.
By turning on the "Disable inline Youtube previews" option, this behavior will be disabled.
Example - Inline Youtube previews enabled
Example - Inline Youtube previews disabled
Same page as above, but with the "Disable inline Youtube previews" option turned on.
