connectors between groups misplaced (regression)

[Saka Nakai]

steps I followed:
- drew a image partly by using connectors
- exported the image to a png
  (see attachment proc-vw-id-auth.png)
- saved the image
  (see attachment proc-vw-id-auth.svg)
- loaded the image
  now 2 of the drawn lines are misplaced presumably to the origin of the image (0,0)
  one can see thios clearly when png and svg are compared

argh ...

not reproduced with Inkscape 0.47 r22583 on OS X 10.5.8
reproduced with Inkscape 0.47+devel r9231, r9297

Moving the two groups with the label 'Authorisatie' and 'ID-mgmnt' inside (e.g. with the cursor key up and back down) triggers a recalculation of the connectors and redraws them correctly.

Yep that worked. Beats redrawing the lines :-)

Thanx

This regression was introduced by a change committed between revision 8853 and 8865:

not reproduced with 0.47+devel r8853
reproduced with 0.47+devel r8865

see also bug #552289 comment #4 describing another regression (misplaced disconnected connectors inside transformed groups) possibly due to the same changes.

Similar to bug #702234 “Incorrect routing of multi-layer connectors on load”, the incorrect routing of the connectors after loading the file seems to depend on the stack order of the connected groups:
If one of the connected groups is below the connector line in z-order, the connector is incorrectly rendered.

Attached file (the connectors are above the connected groups) renders correctly in Inkscape 0.48.0 and 0.48+devel r10005 on OS X 10.5.8, but not in Inkscape 0.47.

[su_v (suv-lp)]

Version 2 of restacked connectors and the connected groups works both in 0.47 and 0.48(+devel).

I'm unable to replicate this issue in Inkscape 1.1-dev (2a5d477, 2020-01-18), Windows 10. If you can still replicate the problem with your file, please comment at https://gitlab.com/inkscape/inbox/issues/1963 which is a related issue.
