Local surrounding gets wrong Translation values when changing them via floating Object editor dialogue

Description

You can manipulate the Translation values of a Local surrounding within the Transformation tab of the Object editor window.

There are two different ways to open the Object editor:

1. Dockable Object editor window: accessible via Window menu, changes dependent of Scene tree selection
2. Floating Object editor dialogue: opens via double click on Scene tree object; for each Scene tree object an extra dialogue appears

Changing existing Translation values of a Local Surrounding via the floating Object editor dialogue can lead to wrong Transformation results.
