Related: tdf#93676 special 255 Percent Flag should not be exported to docx

as a true percentage value. 255 is a special flag that the value is synced to
the other dimension. Without this word gives the frame in the attached example
a huge height.

(cherry picked from commit b2ad33fd5a1ee0cd9a1e657725aedc90da659f24)
