DeviceOS 5.6.0 using System.on(button_final_click) and "2-click" operation?

[jimini]

I have some code migrating from Gen2 and Gen3 devices now running on Photon2 devices using OS 5.6.0. I use Mode button single and double clicks to boot up the device into different operational modes.

System.on(button_final_click, buttonClickHandler);

It works for single and triple clicks of the Mode button, but fails for double clicks. When double clicked the Photon2 resets and extinguishes the LED and sits is in an inoperable state.

Feature or Bug? (A bug in my case...)
Any assistance or documentation cite appreciated.

I found this post that explains what's happening:

Cloud disconnects when multiple Mode button presses encountered with photon 2

Tapping the MODE button twice on the P2 and Photon 2 cause soft power off, like the Electron. I'm not sure why it does that, but it does and goes into HIBERNATE sleep mode and you need to reset the device or remove power to get out of it. One MODE button tap is the signal strength indicator. Cellular devices do that, but Wi-Fi devices like the Argon did not, but now the P2 and Photon 2 also show RSSI on one MODE button tap like cellular devices.

The operative verbiage is "I'm not sure why it does that"...
My bug assertion still stands.
