Can't drag position-locked audio clips to Matrix?

[Starship Krupa 3,306]

Really? Is this as-designed? Or a bug or just an oversight?

A pain, as the first time I noticed it, I was dragging an audio clip to drop it onto a Matrix cell and flubbed it and the clip moved in the timeline a sixteenth or so. Next move was to Ctrl-Z and put position locks on all the clips I wanted to Matrixize. 'cause I wanted to prevent it from happening again, right?

It's odder still because I could Ctrl-drag those locked clips to copy them elsewhere in Track View. I didn't like that they copied as locked, because I wanted to scoot them around a bit, the inability to drop them into the Matrix was worse. The former is easy enough to remedy with a right click or keystroke, the latter not.

Both Documentation and Ref. Guide are silent about this phenomenon.
