I drag&drop an image into a presentation, then try to rescale it with "erweiterte Einstellungen des Bildes" (extended image properties?) right-click menu.
The chain-icon, indicating that aspect ratio should be locked, is clicked.
If i now enter any value for "width", then "Height" is automatically adjusted.
BUT the aspect is wrong. It seems to be 1:1 by default, even when the picture is a different aspect. Suddenly i have a square image.
I have to click the button "Standardgröße" once for the dialog to take the correct aspect into account.
looks like the aspect value is just not calculated as the dialog gets initialised.
