Codesandbox Case (Bug Reports)
Please fork the codesandbox below and create a case demonstrating your bug report. Issues without a codesandbox have much less possibility to be reviewed.

https://codesandbox.io/s/primereact-row-grouping-forked-8kh03?file=/src/index.js

Current behavior
Row grouping breaks when pagination is also added to table. Rows group correctly on first page, then when a user navigates to another page, row grouping breaks and there is a new grouping for every row (See codesandbox supplied above)

Expected behavior
Row grouping should sort all pages grouping into one group if the group by fields are the same.
