Revert "tdf#108932 - prevent textbox shrink from actually growing"

This reverts commit b55d8661 which
was a trial attemp to fix a regression from tdf#91260.

Not reverting my jenkins comment that "Actually, I think that
the regression commit ought to be fully reverted. It "fixes" such
a strange situation and seems to have a lot of unintended
repercussions. Just look at tdf#91260 and see all of the
additional patches."
