Images jumps down when dragging from a palette

Nightly, October 28 (4be8014) / Windows 7

1. Create an image with the screenshot mode to illustrate the execution of a trill, e.g.

2. Save it in a file -> then use it by dragging on the score -> again, drag and drop in a palette for reusing it later.

3. For test, a last time, drag and drop this image from the palette on the score

Result: it jumps one or two systems down. But, according to the layout, and if you reproduce the same action for the notes located more to the right, these images are lost.

Workaround: select the concerned note, and double-click on the image in the palette. This image goes near the note, just below it.
