Besides standard properties for symbols, the Property panel also contains a
checkbox for turning scrubbing on and off in the Playback section. When en-
abled, you can scrub the playhead on the Timeline, and the playhead for the
symbol will also be moved. When this option is unchecked, the symbols do not
change in the Stage preview. However, this switch does not affect the behavior
of symbols at runtime.
