What does 'updatableScroll' on virtual list really do?

Questions

Hello.

I see virtual list has the updatableScroll property.

Its description says:

Is the current device updates and handles scroll events during scroll. By default (if not specified) it is “false” for all iOS devices with iOS version less than 8.

But I simply don’t get what it is trying to say.
Furthermore, I don’t know when I am supposed to use it, and what are the implications of not using it.

Thank you.

In iOS < 8, webkit and UIWebView didn’t fire “scroll” event during intertia scrolling, means there was no updatableScroll. If don’t know about such issue in old iOSes then just ignore this parameter
