reaper.GetTrackStateChunk doesn't return track automation envelopes data

I cannot use GetTrackStateChunk in any of the scripts until this is fixed.

When using reaper.GetTrackStateChunk, the chunk string returned doesn't have any <PARMENV > data.

Step to reproduce:
make a track with a plugin and some automation on some of its parameters for example.
Run this script on the track.
Result:
it removes all automation lanes on the track!

Code:

---

retval, trackchunk = reaper.GetTrackStateChunk(reaper.GetSelectedTrack(0,0), "", true)
reaper.SetTrackStateChunk(reaper.GetSelectedTrack(0,0), trackchunk, true)
