This is seriously blocking me from seriously considering Opera as my browser across almost all devices I have. In desktop, embedded tweets display like this:

This is the same thing in Safari:

I don't have this problem in Chrome (desktop, chromebook, mobile), Vivaldi, Firefox (desktop, mobile) or Opera Mobile when I have third party cookies enabled. I currently have ad-blocking disabled and third party cookies enabled on desktop, but embedded tweets still don't display correctly.

I am having the same issue in the Developer Edition.

Neither Google nor a forum search has given me anything specific to Opera. Can anyone help?
