Two chrome defects, one root. The layout code that decides where the tab strip ends and where a click lands sized the update button at a fixed icon width, while the painter drew it wider once an update was installed and waiting for a restart.

The tab strip now reads the button's real width: when Restart (or any wider control) appears, tabs shrink and collapse into the overflow menu instead of sliding under the buttons.

The click zones follow the drawn geometry again, so pressing Restart no longer opens the blog through its left half — each button answers exactly where it is painted.
