[TC-I-2.2] identify-time Attribute is not correctly decrementing over time

[joesena-amz]

Test Case ID:
[TC-I-2.2] Primary functionality with server as DUT

Describe Issue:
After running the steps Steps 2c and 6b, the identify-time attribute is not correctly decrementing over time as it should. For example, Step 2c runs 10 seconds after running Step 2b, so the identify-time attribute should be around 50 seconds, but the attribute value does not decrease at all with time, it remains at 60, where it was set in Step 2a.

Same thing happens after running Step 6b 5 seconds after Step 6a, the attribute value remains at 15 seconds.
The logs all indicate the test steps are successful, but they are not.

Step 2b in logs: [1634763074.402461][1157072:1157078] CHIP:TOO: Int16u attribute Response: 60
Step 2c in logs: [1634763088.932205][1157224:1157229] CHIP:TOO: Int16u attribute Response: 60
Step 6a in logs: [1634767492.846470][24351:24351] CHIP:DMG: Data = 15,
Step 6b in logs: [1634767518.583540][1193780:1193785] CHIP:TOO: Int16u attribute Response: 15
