blockOuterScroll behaviour - scroll is jumping

Hello!

Scroll is jumping sometimes in our portal.
I tried to investigate what causes this behaviour.

react-custom-scroll/src/main/customScroll.js

Line 277 in 1f47571

const delta = e.deltaY % 3 ? e.deltaY : e.deltaY * 10

Changing this line to const delta = e.deltaY can fix this behaviour.

Please explain what is behind this mathematics(% 3 and * 10).

This issue would explain the problem I'm currently having with this package. Any reason this issue has been untouched for over a year? It seems like this is a problem that would be affecting everyone using this package, so it's strange to me that it hasn't been addressed.

@cuteapoot The problem of blocking outer scroll was very difficult to solve, as I needed to identify this scroll event is about to reach the end of the scroll area, before applying the scroll and block it.
At the time, calculating how much pixels will be scrolled required the % 3 check to identify Explorer browser, which used different units.

I just found that there's a css property that didn't exist when I created the library called "overscroll-behavior-block" and it seems it is supported in all relevant browsers.

I'll try to implement it instead of this calculation and publish a fix

Just released v7 that contains a fix for this problem
