Related fdo#69006: Reintroduce some height calculation back.

When importing CSV with multiple lines in a cell, it looks as if some content
was lost.  It is not, it is in the spreadsheet, but looks very confusing, and
only way to get around that was to let the heights be recalculated.

It seems that the large CSV still opens in reasonable time even with this
change in.
