Apply Track FX... broken if playback rate other than 1.0.

Steps to reproduce:
- Set playback rate to 2.0.
- Right click the slider and check "Preserve pitch..."
- Apply track FX to an item.
- Play.

The pitch of the item is now down one whole octave.


Edit: Just to clarify: If the playback rate is set to 1.083, the pitch goes down about a half note (language barrier: I mean semitone, 1/12 of an octave), so the pitch correction is doubled, sort of.

Unchecking "Preserve pitch when changing rate" before Applying FX, and checking it back on right after is a temporary solution for the issue.
