please see my comment here #9437 (comment). I think it would be better to override browserActions with new tabAction data then other way around. This way if browserActions and tabAction have the same value we would use tabAction's value.

I just tried it again and this fix fixes icon problem, but if you click on an icon nothing happens. But if you click on an icon when you are on new tab, popup is shown.

@NejcZdovc This PR is meant only to resolve the missing icon issue. I'm going to look into the reason behind unresponsive icons next. Also testing the latest version of bitwarden in the process; attempting to take out as many birds with as few stones as possible :)

@NejcZdovc looks like you missed 0.20.x when cherry-picking into branches. I went ahead and made sure it's included in there: e4e0cf6

BTW- awesome job knocking this out, @jonathansampson 😄

 @bsclifton you are right, I forgot that we are already on 0.21 😄 thank you
