SCXML Designer sometimes reorders states in the XML file

The image below illustrates the problem. The background window is QtCreator 10 with a SCML state machine and the forground window is the diff after doing this:

• move the circled state a bit left with the mouse and save
• press Ctrl-Z to make it move back and save

Then the XML section for the moved-and-reverted state for some reason moved below the other substates if Processing.

When such a move-save-revert-save sequence happens when you want to change an onEntry script of a state, the real change in the script is not visible when diffing the code, as the diff tool just sees one big block being deleted and another big block being inserted.
