bestFitVertical.xlsx: MSO bestFit inconsistency demo
Slices near the Y-axis are best suited for well-wrapped text. Unfortunately,
LO's algorithm has no ability to look for the "best width". So it cannot place
as many labels inside the slice as needed for compatibility documents.
However, there are other cases where LO's algorithm is able to bestFit content
where MSO fails, and as this document shows, MSO isn't very predictable in
determining whether content should bestFit or not.
Fixing this will require adding a significant amount of intelligence to the
bestFit algorithm. It will need to loop and try three or four different widths.
Due to 3D manipulation, simple tricks like comparing the slice area to the text
area will not work - unless your area formula takes into account the 3D
rotation.
