Testdocument whith original content and distorted image after *.png-export

Open the attached Draw-file.
There is a screenshot imported into Draw. Some elements have been added to the screenshot. Then the screenshot has been exported with this element.

The filter sets the right width for the visible area in Draw. But the export will also recognize there had been a transition-point for an arrow outside the marked area. So image will be distorted. The width isn't shown in the right width. The exported *.png-file will get a transparent area at the right.

Expected behavior: When exporting a selection to a pixel image the construction mustn't be exported. The image shouldn't show the content distorted. Only the visible marked area should be exported.

This buggy behavior appears in LO 6.4.4.2 on OpenSUSE 15.1 64bit rpm Linux.
