File causing CPU hit

Attachment is taken from bug 60118, re-attached for convenience as the original was an archive.

I sometimes observed that with my wide desktop screen, having Calc maximized prevented the CPU hammering. Thus, it is best to resize to a size where you don't see much of the grey background on the right.

Bibisected with win32-6.3 to https://gerrit.libreoffice.org/plugins/gitiles/core/+/d464d505fbf6e53a38afdd3661d320fac8c760d6%5E!/
