bending line example

Attached file is simply a two rectangulars connected this manually stretched-out connection line.

1) make sure file is editable, open file, move any rectangular a bit, bending connector retains its stretched-out to right oval shape, which is correct, don't click 'save' button
2)  click 'close' Draw application, a dialog appears asking for saving file, click 'yes'
3) open file again, start dragging rectangular again, bendging connector loses its stretched-out shape, which is not correct.

So the behaviour in Draw is inconsistent.
* In case user first saves file and then closes the Draw application further opening&editing file is okay.
* In case user closes application and chooses to save file further editing file is not okay, i.e moving objects causes connection lines drop its shape, which is very annoying (moving one object causes all lines to change their shapes to default bending form)
