Here's these changes are supposed to do:

  * put the synopsis back on the right side
  * properly have it on the edge of the screen on wide screens
  * adjust the background of the synopsis to match the button
    (otherwise the grey blends in with what is underneath)
  * get rid of the dotted purple line
  * the synopsis contents are now scrollable even when in wide
    screens (this has been a long-standing bug)
