(Bug) Scroll icons are present behind table header when using fixedTables and Bootstrap (Firefox)

Kagrenac

it might be my version of Firefox (version 54.0) but I thought I should note that when using this initialization of datatables

$(clonedTable).DataTable({
searching: false,
scrollX: true,
scrollY: "300px",
fixedColumns: {
leftColumns: 2
}
});

there is a up and down scrolling area behind the headers of my table.

This is also present in the FixedColumns/Bootstrap page here
https://datatables.net/extensions/fixedcolumns/examples/styling/bootstrap.html

I only encounter this in Firefox, it doesn't happen in Chrome or IE.
This is my first post so I'm sorry if it is scatterbrained, I just wanted to put it out there. If you need a screenshot of it happening on the DataTables/FixedColumns/Bootstrap page let me know!

Thanks,
Devin
