Bug Report

Package versions:

devexteme version: 21.1.5
devextreme-react version: 21.1.5

Steps to reproduce: https://codesandbox.io/s/fancy-dust-le72h

Current behavior:

If I use shadow dom, most of the function does not work: resize columns, reposition columns, edit cell by double click, select row by click and others. I try to use library [email protected] and I also try to use directly attachShadow, but I have the same result - it doesn't work. I tried to solve this problem by myself, and I found out that instead of CustomEvents I get standard onClick. But I don't know how to fix it.

Expected behavior:
