Fix the position of the Reference marker (SA Mode ONLY)

trace when the marker was created, or it can ‘float’ with each sweep at the
Y-axis position of the data trace. In CAT and NA mode, the reference marker
always floats with the data trace. This setting applies to all SA markers.

trace when the marker was created (default SA mode).
