Test Spreadsheet to demonstrate the bug

I noticed several spreadsheets are become unresponsive when scrolling with the keyboard. 

Steps to Reproduce
1. With a recent build of libreoffice open the attachment
2. Put the cursor in N1
3. Press the down arrow to make the screen scroll

Actual Results:
1. Usually by the time you hit N39, the LibreOffice UI will freeze and become unresponsive for several minutes.

I was able to reproduce this on a Win 10 desktop and laptop with 64bit builds. So far I have bisected the regression down to this range:

Comment 1 Luke 2017-07-18 06:45:43 UTC 
Also seeing this on: Version: 6.0.0.0.alpha0+
Build ID: 7a743b472dadb817eb7a6ed8063cee80ce7412e8
CPU threads: 4; OS: Windows 6.19; UI render: GL; 
TinderBox: Win-x86@42, Branch:master, Time: 2017-07-17_23:50:28

So it affects both x86 and x86-64.

I bisected this regression down to this commit:
