Orientation of extension-created objects should not be turned, if the group was turned

Summary:

When the user is inside a grouped object which was turned for 180 deg and adds a new object, the new object is sometimes turned too.

This is not consistent as the attached .svg shows.

Object is turned, if the group was turned LaTeX: YES QR Code: YES Text NO:

Steps to reproduce:

• open Inkscape
• create two objects and group them
• turn the group by 180 deg
• open the group with double click
• Extensions > Render > Mathematics > LaTeX (pdflatex)...

Result: Inserted formula is rotated 180°

Expected: Inserted formula is not rotated
