There is no way to determine this information. The argument passed to
`events.UPDATE_UI` will let you know if the content itself changes, but
not what that content was.

You'll have to save them in an `events.BUFFER_BEFORE_SWITCH` event and
restore them in an `events.BUFFER_AFTER_SWITCH` event. See `core/ui.lua`'s
event pair for saving stuff like folds.
