[Modal] Issue with overflow-y: scroll on <html> #34513
Description
Summary 💡
Add scrollContainer to support custom scroll lock containers.
Examples 🌈
Our product is a browser plugin that enables some features on social platforms. We have implemented some features on Twitter and used dialog. But since twitter implements overflow on the html node.
Motivation 🔦
However, scrollLock currently only works on the body node. And developers cannot customize the nodes that require scroll lock.
So I implemented a simple patch.
