Dropping "Image" on note attaches it to segment instead.

1. write a note that lays inside the staff (eg. f4 to e5 for treble clef)
2. drag an "image" from a palette and drop it on the note head (only reproducible with an "image" tag in the palette: use the attached palette as an example).
3. the note head is highlighted (blue), which visually indicates that dropping the element will attach it to the note.

Result: the image is attached to the note's segment instead (clearly shown by the dashed line that appears when dragging the image). Moving the note does not move the image; removing the note does not remove the image.

Expected: the image is attached to the note (head). This is what happens when the note head lays outside the staff (e.g. c4 in treble clef) and is perceived as the correct behavior.

(side note: when typesetting 1900s/contemporary music with extended techniques, one often needs to draw his own symbols as svg images. Attaching them to notes is required for articulation symbols etc. That motivates keeping this existing feature polished and reliable).
(other note: in musescore 2, the expected results is sometimes (randomly?) obtained)
