Currently, the captions menu (::-webkit-media-controls-closed-captions-track-list) has "max-width" and "max-height" set to 250px. When the captions name are long, it may happen that the name of the caption is clipped even though there is plenty of space available to display the full title over the video. The max-width and max-height of the captions menu should be dependent on the available video real-estate.
