The worst thing about trying to make something work in the browser for mobile is getting the UI to utilize the full height. This is common when the UI needs to have both something stickied on the top and bottom of the page. Both Chrome Android and Safari will cut off content if that content is 100vh with their URL bar that comes and goes as you scroll. Then you have full screen mode which iOS does not support but Chrome does, except that on Chrome invoking the keyboard does not tell the page anything about the height that it's taking up.

The only browser that gets everything correct is Samsung's default browser. This is pretty ridiculous and the hacks available with current APIs aren't very good compared to if these browsers worked properly with 100vh.
