[LED2106R3] Not joining the network #30959

What happened?

I recently bought some IKEA Tradfri GU10 bulbs, as I'd rather hold of a bit on the new Kajplatz (or however you spell it) ones. I also have a bunch of the IKEA Tradfri bulbs in the network.

I bought a Tradfri GU10 "Starterkit", which includes a remote and 3 LED2106R3 bulbs.
I also bought 2 seperate 2104R3 bulbs and a Hue Dimmer Siwtch.

When trying to pair, I would reset the bulb (7x off and on) and it would go into pairing mode.
However, it would never report to Z2M or pair at all. Not even a blip in the logs.

I tried it a the spot where they are supposed to hang, I tried it near the coordinator, tried the allow join set to "all", tried the allow join set to a specific device, but nothing.

When I tried to pair the Hue Dimmer Switch, it joined without issue. When I tried the 2104R3, it also joined in an instant.

I've tried reverting back go 2.7.2, but to no avail.
Also updated the coordinator firmware.
Have not tried the dev-branch yet, will do that tomorrow, but not expecting any miracles.

What did you expect to happen?

I expected the bulb to join without issue.

How to reproduce it (minimal and precise)

Reset the lightbulb
Wait for it to pair
