This is a follow-up bug of bug 101195

Steps to reproduce:
1. Open http://rkb1c.ru/soft/35mb.xls. it should be around 25 seconds in master after https://gerrit.libreoffice.org/plugins/gitiles/core/+/af84fc9d906626255aaf136eefc5e55236e0e8a6%5E%21 and noel's improvements

Doesn't seem laggy to me. Xisco: can you re-test?

Hi Xisco, this file opened really fast for me (less than 5 seconds) using LO 7.4 alpha. And scrolling is super smooth.
