bug - detect scene cut on layer 2

v1/v3/v4/v5 are filled with clips and locked.

v2 i put a long clip the need cut

select the clip and [detect scene cut] does not do anything if auto track selector for v2 is not on.

there is no such restriction in the manual:

1 Select one or more clips you want to split on the Timeline
2 Choose Timeline > Detect Scene Cuts.

Actually it does not seems to care which clip I select (in Linux) it does all the clips in the laters that are flagged regardless fo the status (hidden/disabled/layer locked)

This seems very wrong.
