[Test Failed] TC-GRPKEY-2.1 step 3 fail

Test issue(s)

1.TC-GRPKEY-2.1 step 3

Platform

core (please add to version below) - Matter 1.4 SDK

Anything else?

When the test is run for already commissioned DUT, then current fabricIndex != 1. In step 2 there is write command to fabric 1 performed from different farbic (5 in my case):
Command: groupkeymanagement write group-key-map [{"fabricIndex": 1, "groupId": 259, "groupKeySetID": 419}] 0xf16b268c6956dec3 0
Actual write is done fabricIndex 5, because SDK discards the requested fabricIndex and uses aDecoder.AccessingFabricIndex():

And in step 3 there is:
Command: groupkeymanagement read group-key-map 0xf16b268c6956dec3 0
And fails expected value check:
Test Failure: The test expectation "value ([{'GroupId': 259, 'GroupKeySetID': 419, 'FabricIndex': 3}]) == [{'FabricIndex': 1, 'GroupId': 259, 'GroupKeySetID': 419}]" is false

In my opinion WriteGroupKeyMap() method need to use requested fabricIndex instead of aDecoder.AccessingFabricIndex().
