Has there been any movement on this. There has been a few updates to Vivaldi and still no mention of this.
It is still on going, and it seems to really happen / trigger upon clicking on links within the page that open a new tab. I noticed that as @LonM mentioned, other tabs are incredibly slow to load some times. I have been tempted so many times to go back to chrome. I really don't want to, but this workflow is killing me.

Any help would be appreciated.

Also @AGoodGeek's workaround didn't work unfortunately. So i have stuck to cloning the tab and closing the old infected one.

Thank you again!
