Is there a way to replicate Zen browser's title bar behavior in Vivaldi?

https://docs.zen-browser.app/user-manual/bookmarks

The way the title shows up on hover only in the main window and not in the tab panel and hosts the bookmarks bar in Zen is so perfect, its hard to live without it. I love Vivaldi otherwise!

Is there a way to make it work the same way in Vivaldi? Using CSS or something?

Current Vivaldi implementation (ver 8) is very much in the way and useless.
