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.
