  // When modal sheet is presented, for the duration of the animation the run loop
  // is running in _NSMoveTimerRunLoopMode. This prevents Flutter content from
  // being rendered. The solution is to add _NSMoveTimerRunLoopMode to common
  // run loop modes, but referencing it directly may be flagged as SPI usage.
  // Instead as a workaround a very short window zoom animation is triggered, which
  // runs in _NSMoveTimerRunLoopMode adding the mode to CFRunLoop all modes list.
  // After that it can be queried and added to common modes.
