Error when Remuxing 24bit PCM Audio in Quicktime format

MKVToolNix can't recognize 24bit PCM Audio correctly in this situation. The output file results in unrecognizable audio track in PotPlayer and white noise in MPC-HC.

It seems that the 24bit audio track has been recognized as 16bit as #2228 (closed) mentioned. I opened this issue because the previous one has no update for a long time.

MKVToolNix version: 25.0.0
