Description

I'm using cdk-virtual-scroll-viewport with mat-table. I have the first and last column as a sticky(sticky for first and stickyEnd for last). Also, I have row selection. So when the user clicks the row it's highlighted. And when I select some row and then start to scroll virtual scroll starts jumping around
