IC-7300 PASSBAND_NOCHANGE not working correctly

[mdblack98]

Hi!

Workflow:

issue command:  +\set_mode currVFO USB -1
manually set filter other than #1:  set filter #2
issue command:  +\set_mode currVFO LSB -1

Bug:

filter returns always to #1 when sideband changes.

Setup:

Icom IC7300 firmware 1.41
rigctld Hamlib 4.6~git Jun 05 13:34:59Z 2023 SHA=acc426 64-bit
Fedora release 37 (Thirty Seven)

Question:

Bandwidth "-1" should keep the selected bandwidth, this case keep

selected filter #2, but it does not.
I understand that filter resets to #1 when mode changes (CW->SSB,
SSB->AM etc.) but this case mode is same SSB, just sideband changes.

Is this a bug, intentional feature or Icom property?
