Hulu Pausing causes subtitles to disappear & replaced by a rewind, play, fast forward overlay

On Hulu, subtitles disappear when you pause and are replaced with essentially a "rewind, play, fast forward" screen over the subtitle area.  It defeats the purpose of the "Pause" to read what is on the screen.  So you have to go back several times to read a long subtitle.  Is this a Roku or Hulu issue on a Roku device?
