KiCAD6 adds automatically connections (knots) to schematics when opening old KiCAD5-project
Description
I have a KiCAD5 project were the schematics was drawn "dirty": wires are crossing wire ends of other parts. When drawing there will be automatically knots set - but you can remove them and you can work with the schematics. You can close and open it and the knots will ever be removed. If you open such a project using KiCAD6 schematics will automatically have added connections (knots) without asking. This destroys the schematics.
Steps to reproduce
Look at the screenshot - that is the result if I open a functioning KiCAD5 schematic in KiCAD6.
