Open Doesn't play well (at least with Sync enabled) with Vivaldi (a browser built directly from Chrome)

Hey Joao! I know that this browser isn't exactly supported, but I did find something very strange today once I updated the snapshot version [1.14.1077.39] of Vivaldi. The Join Chrome extension would essentially break (None of my devices show up nor any of the settings menu items work properly) when I was using the snapshots that had Sync (a beta feature, which has some bugs of course), once it was disabled in the fairly recent snapshot update, it made the extension work like normal. I did throw this bug report over to the Vivaldi developers themselves to have a look at it, I just felt that you needed to know about it too.

 

I'm using Vivaldi 1.14.1077.50 and the extensions is not working here too.
do you know which Vivaldi version supports the extension?

 

I'm not at my computer at the moment but what I do know is if I keep Sync off (and reset some browser data), the extension functions again

The version doesn't seem to matter at all, but the key thing that matters is having Sync on at all affects it
