core: Can't connect to Emulated hue from Harmony hub

The problem

I can’t pair the emulated_hue bridge to my harmony hub using the harmony Android or iOS app. I have tried using the default port and port 80. The problem seems to have been introduced with 0.110.0/0.110.1 because when I download the component source files from 0.109.6 and set it up as custom_component, I was able to pair the bridge just fine. I suspect the issue has been introduced with https://github.com/home-assistant/core/pull/35148. I noticed the PR comments about the harmony tests, but it looks like it’s still an issue. I have added my harmony hub software version below.
