[bug] Grouped objects are duplicated in the SVG

Grouped objects (through Ctrl-G) are duplicated in the SVG.

This is how it looks when the SVG is loaded into Inkscape (rectangle and circle are grouped together):

I tried 2 ways of exporting an svg for the provided file, then imported them in Figma (each pair of vectors are the stroke + background):
