Testing with a JBL SB400 BT on a Lenovo Thinkpad T450S with the intel ibt driver on F/W version 37081001103110e23 works correctly.
Doing a parallel test on my laptop (HP evo 850) that has :
[12383.666088] Bluetooth: hci0: read Intel version: 370710018002030d00 [12383.666095] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
Fails according to the bug report.
So it may be firmware related
