Connectors don't correctly connect to group with preserved transform
Migrated from: https://bugs.launchpad.net/inkscape/+bug/617810
Steps to reproduce:
- open Inkscape
- create an ellipse
- flip it vertically to create a transform attribute
- group the ellipse
- create a second object
- connect the (grouped) ellipse with the second object using the connector tool
- move the ellipse around
What happened?
The connector doesn't stay connected to the ellipse.
What should have happened?
The connector stays connected to the ellipse.
Inkscape Version and Operating System:
- Inkscape Version: 1.1-dev (12e2a09, 2020-02-19)
- Operating System: Windows 10
- Operating System version: 10.0.18362
Replicated since Inkscape 0.47, apparently a regression from 0.46.
Sample file from Launchpad with different test cases:
The error in Inkscape 0.47 seems to be in incorrectly handling nested preserved transformations (the group as well as its child each have an explicit 'transform' attribute). Once I converted the child of each group to a path and forced Inkscape to rewrite its path data (the transformation is now 'optimized' and stored in the node coordinates), the connectors in 0.47 behave like in 0.46 when moving a group with an attached connector
