OSBA 128kbps JBM - Saturations across whole signal

Basic info

• Encoder (float): d9fdb374
• Decoder: 2978a304

Bug description

When decoding OSBA with JBM at 128 kbps (pre-rendering mode), we see severe saturations across the complete file, resulting in high MLD diffs.

Float (Channel 5, i.e. omni channel):

BASOP (Channel 5, i.e. omni channel):

Decoding the bitstream w/o JBM (i.e. a bitstream without any delay/error profiles) works just as expected.
