Native menu bar and context menus are very much built into Electron, even Hello World will have a proper menu on macOS. Some of the stuff like integrated title bar is also pretty recent, and likely wasn’t a contributing factor to its adoption. Not to say VSCode doesn’t put any effort in or anything but I think Electron apps are about on par with Qt apps in terms of native look and feel, albeit they have their own strengths and weaknesses and are not easy to directly compare.
