When restoring a terminal * it is best to do before `Terminal.open` is called to avoid wasting CPU cycles rendering * incomplete frames. + * + * It's recommended that you write the serialized data into a terminal of the same size in which + * it originated from and then resize it after if needed. + * * @param scrollback The number of rows in scrollback buffer to serialize, starting from the * bottom of the scrollback buffer. This defaults to the all available rows in the scrollback * buffer.
