(NO BUG)API: SetTrackStateChunk doesn't update FX CHAIN SHOW parameter
If you get a track chunk and set FX CHAIN SHOW parameter to 0 and will get track chunk again, SHOW will be not 0.
So setting this parameter to 0 should hide an fx chain, but it doesn't.
Tested on 6.23 version 64-bit, Windows 10 Pro.
