(Marking as 84, but the platform team should feel free to re-triage this one…)

This seems like a minor cosmetic issue to me. Arguably, this is an author error. I doubt that Youtube intended to have the Search bar show up in print layout at all, or at least not on every page.

The missing placeholder text might be related to bug 1034307.
