trackData on all track types except "CompositeTrack" returns an
object that inherits GRanges class, which means they should behave like a GRanges.
While trackData on "CompositeTrack" returns a list of tracks.
track <- BlockTrack(GRanges("chr1", IRanges(6, 54)))
trackData(track) # track data of block track is an object that inherits GRanges.
ctrack <- merge(track, track)
trackData(ctrack) # track data of composite track is a list of tracks
