Rows filter

Hi,

I am using below method to collapse a Cell

function collapse(n) {
  if (fieldsToExpand.length == 0) {
    let slice = pivot.getReport().slice
    fieldsToExpand = slice.rows.splice(-n)
    pivot.runQuery(slice)
  }
}

But it seems that its not taking filters added on Rows and thus providing incorrect result. How can we fix it?

Thanks,

Varun
