<theoplayer-preview-thumbnail> - A display that shows the thumbnail image at the current preview time
of a <theoplayer-time-range>.
The first metadata text track whose label equals "thumbnails" is used as source for the thumbnails.
This track is expected to contain cues whose content is the URL for the thumbnail image.
If the thumbnail image URL ends with a spatial fragment
(e.g. #xywh=180,80,60,40), then the thumbnail is clipped to the rectangle defined by that fragment.
If the stream does not contain thumbnails, then this display shows nothing.
