In Safari there is no transition. The viewport height snaps between svh and lvh at the end of the browser's chrome collapse/expand animation. I don't have an android phone to check the Chrome's implementation, but I imagine it working in the same way, since animating the heights of potentially all the elements in the page can not be done in an efficient way by the browsers, and having a stuttery scroll as soon as you start scrolling a web page would not be a great user experience.
