NestedWebview's Scroll not same as in CollapsingToolbarLayout

[kelalaka153]

I've come into this library with stackoverflow suggestions to Android bug with Webview and NestedScrollView.

The replacement is very easy and I've got rid of the app crush on large web pages. However, the scrolling not same as the default CollapsingToolbarLayout.

1. The webview scroll into the CollapsingToolbar as soon as scrolling started.
2. The CollapsingToolbar coming down very fast on down scrool

I think the CollapsingToolbar and the webview scrolls together.

Can we solve this?
