Description

After connecting two shapes with Blend Shape node their pivot change location. This should not happen, as it changes how original objects could be snapped or rotated.

Before:

After:

The only thing that I did was to add a node here:

Removing the node moves pivots back to their original placements.

Tested with build: https://d13f5c46.graphite.pages.dev/ on Chromium Version 142.0.7444.175 (Official Build) built on Debian GNU/Linux 13 (trixie) (64-bit)

Research direction

Reproduce the pivot movement by connecting two shapes with a Blend Shape node in the reported Graphite build, then compare the pivots before and after adding and removing the node. Trace the Blend Shape node's transform handling and verify that original object pivots remain unchanged while snapping and rotation behavior are preserved.
