Unable to move sketch due to history dependency

Hi,

Looking for an explanation why Sketches can’t be moved together with other object which are completely unrelated to the sketch? (I know the debate about moving bodies and relative sketches at the same time, which this is not the case).

Please see the video below.

I have one sketch which is based of an imported image. Now when i try to move the sketch (and the image file) so that the sketch stays in correct position as overlay, i get the error “Can’t move due to history dependency….” Error. However each can be moves separately.

There are no bodies extruded yet, image file is unrelated to sketch, yet impossible to move.
