Edge Dev/Canary enterprise extension sync broken?

I noticed on my test system that setting up a new profile in Dev/Canary sync doesn't work correctly - specifically, extensions do not install properly. In my stable channel build everything is working, however when it attempts to sync to Dev/Canary only the "forced" extension I have enabled via policy shows/works, where as the others are not in the extension list, but are present in the AppData user data folder. I've attempted to reset sync and have everything get pulled down again, but the issue persists. I've tried clearing out the profile and re-installing Dev/Canary to see if having it force re-sync would help, but it does not.

TLDR - syncing extensions to dev/canary with enterprise sync breaks any extension that is not 'forced' to install via policy
