Subject: issue #7583 External Links in Inheritance Diagrams open in the Image
 Frame.

When having a function it opens in the current frame and uses the complete frame. Images (e.g. inherited diagrams) are displayed in a small "sub frame" and when displaying the link here it is not readable and furthermore the user doesn't know anything about the "sub frame". In case of an image the link should be displayed in the parent frame of the image.
