Problem with backspace on Flash site
I've been having a problem when using Vivaldi with a flash based site that has messaging. When I am writing a message and make a mistake, and I press backspace on my keyboard, instead of deleting a character it activates the back button in the browser. This is most annoying since it means I lose the message and have to re-navigate to the site. This doesn't happen with other non-flash sites. When I use the site in another browser this doesn't happen, but it is a nuisance to have to do this. Is it likely to be a bug in Vivaldi or the site I'm using? Has anyone else experienced this when using flash based sites?

The easiest thing to do at this point, at least from my perspective is:
