Hi Regina,
In your first mail you mentioned that MSO has viewbox size 43200x43200, while LibreOffice has viewbox size 21600x21600.
And MSO viewbox only contains the current sector but LibreOffice contains the eclipse.
I think it's correct that you want to make LibreOffice viewbox only contain the current sector. But I think the problem is caused by incorrect conversion of the draw:enhanced-path (see the content.xml in saved odt file) instead of the incorrect viewbox size. I think it's important to find out why it failed to convert the enhanced-path so that it only contains the sector.
Although changing the viewbox size might have the expected effect for the arc shape msoSptArc, but I don't understand why it works and we might also miss the chance to fix the conversion of problematic drawing commands for other custom shapes.

But they have different size and position of the viewbox. I have written
https://bugs.documentfoundation.org/show_bug.cgi?id=124029. It has a
document attached, where you can see the problem.
If they don't, I'd consider to

It is only about the shape 'arc'. I do not see the problem for other
shape types. The 'arc' has a special treating anyway, see
msdffimpl.cxx#4513. Setting a special viewbox for the 'arc' shape would
have no effect on other shapes.
There would be a difference for the user. If he changed the angle of the
arc, he would notice, that the adjustment handles leave the rectangle of
the resize handles and the sector might be partly outside the rectangle
of the resize handles.
Or maybe the view port were set to 0,0,0,0 as in

That is in the OOXML import filter and not affected here. The treating
there is wrong, but it is a different problem.
Kind regards
