Blueprint table scrolling problem when using keyboard

Environment

• Package version(s): Blueprint table 3.8.1
• Browser and OS versions: Chrome

If possible, link to a minimal repro (fork this code sandbox): https://codesandbox.io/s/blueprint-sandbox-jt7py

Steps to reproduce

1. Create blueprint table with enough columns so there is a horizontal scrollbar
2. Move the selection to the last column using the keyboard (shift or arrow keys)
3. Move the selection back to the first column also using the keyboard

Actual behavior

The scrollbar does not go back all the way - as you can see in the linked repo for example, when you scroll back to the start, the 'A' of the column name is cut off and you can't scroll further without using the mouse.

Expected behavior

Scrollbar should return to original position without having to use the mouse - this is an accessibility issue.
