This may not be a bug as such, but the behaviour isn't as expected.
to repeat:
1/ click to select a sequence clip
2/ mark an IN point later in the timeline, beyond that selected clip
3/ position the Playhead at the head of the selected clip
4/ position Source viewer Playhead at desired spot
5/ Replace command
result:
The replace takes place at the in point, not at the playhead and not at the selected clip.
It seems that to be consistent with other aspects of Resolve where selecting a clip over-rides track dominance etc, selection should also be first priority here too.
Thanks,
Mark.
