Table with ghost cells continues to scroll when there are no more rows

[mattskrobola]

Environment

• Package version(s): blueprint 4 core and table

Code Sandbox

Link to a minimal repro:
https://codesandbox.io/s/cool-benz-es9oo?file=/src/App.js

Steps to reproduce

Create a scrollable Table with enableGhostCells set to true

Actual behavior

Scrollbar continues to scroll when reaching the bottom of the table. Also grabbing the scrollbar and dragging down creates more ghost rows.

Expected behavior

The scrollbar stops scrolling when it reached the bottom of the table

Notes:
Scrolling over a frozen column to the bottom of the table behaves as normal

I've isolated the bug to occur between table v3.8.0 – v3.8.1

not present in v3.8.0: https://codesandbox.io/s/modern-sound-z9ul4?file=/src/App.js
present in v3.8.1: https://codesandbox.io/s/awesome-rumple-k40zq?file=/src/App.js

From reverting commits locally #3771 seems to be the PR that caused this cc @adidahiya

Fixed in v4 by #5115
