When the Stylebook doesn't have a ruling, we defer to Merriam-Webster. So you're correct - I would hyphenate up-front.

This was a rule at the newspapers I worked for years ago. But people consume digital content different: If it's done well, it should be an immersive experience where each element doesn't have to match exactly (i.e. we don't need an auto-play video explaining how something works and a text box explaining it). In these cases, as long as the pull quote includes the person quoted and their title, it's OK if it doesn't appear in the text. I would also want to be clear if the person is speaking with a specific take. "John Doe, history professor at Oz University, who believes animals should have more rights."  And I'd prefer that the person is mentioned in the story text, even if the exact quote isn't there. 

The guidance remains that if you use a partial quote in a headline or lead, you must include the full quote later in the text. That applies to pull quotes, too.
