Extension links escape Firefox Container Tabs

[patcon]

I use Firefox's new Container Tabs to manage organizational accounts. I log into Twitter and Buffer inside a special Tab Container. I would expect that when in the tab container, using Tweetdeck, that clicking the Buffer extension button would open Buffer in a new container tab (as it does for other target _blank links).

But instead, it opens in a normal tab, and so uses the Buffer account connected to my personal account (the one I'm logged into via Twitter in normal tabs).

Is there any way to resolve this at the extension level?

Thanks so much!

Seems like the fix would just be to query the current container tab, and then use that cookieStoreId to open to new tab.
