[ Maybe a Bug? ] The wrong position of the first tab-hover preview card

[witherzuo]

Version: 87.0.658.0 (canary)

I noticed that the preview card of the first tab-hovered have a wrong position than other tabs, like below screenshots: 

I think the right way is all hovered tabs can show their preview at the correct position.

And...this Canary version changed the position of Show Vertical Tabs button, moved to Address & Toolbar from top-tab bar.

Maybe they left it for vertical tabs. Maybe.
