Unusual scrolling on some devices #1663
Description
Describe the issue
On some devices, when a keyboard pops up upon clicking a blank line, it scrolls abnormally, even in the opposite direction, making the editor cursor invisible. (The right window in the first demonstration in the video). On some devices, it works normally (left window).
The demo code is as follows
import "./style.css";
import { javascript } from "@codemirror/lang-javascript";
import { monokai } from "@uiw/codemirror-themes-all";
import { EditorView, basicSetup } from "codemirror";
new EditorView({
doc: "console.log('Hello, world!');\n".repeat(100),
parent: document.getElementById("editor")!,
extensions: [basicSetup, monokai, javascript()],
});01_1.mp4
Browser and platform
Abnormal device: Xiaomi, Android version: 15 , System version: hyper os 3

To add, this may be related to cr, once in a while, when I paste the code into the editor, I see a red cr logo, even if it is not at the last line or the beginning of a line, as long as I click on this "cr", it will cause abnormal scrolling

I have also faced it even on codemirror.net example with some content which can trigger scrolling on mobile

Seems to only happen in Chrome (and any Chromium's dependents, including Brave, Opera, Samsung Internet, and Android WebView):
