Am I the only one experiencing this issue with #Facebook email-links on @Vivaldi in which I click on a link sent to me in email, it loads up the page in Vivaldi, I see the post for a second or three -- and then the post is replaced by... well, this (see image)? #faceBug
(It works properly in Firefox, but I'm still blaming FB for whatever JS shenanigans they're using that requires tight browser-compatibility instead of just, you know, HTML/CSS.)
