coloring elememets results in relayout with some strange consequences

Better title needed...

• Take the attach score
• right click a clef, select all similar, change color
• right click a key sig, select all similar, change color

Watch what happens in the 3rd line, 1st and 2nd measure, it seems a relayout cause the last measure of 2nd line not to fit anymore, so it moves to the 3rd line, and the (colored) clef and key sig move to the 2nd measure of the 3rd line, the 1st measure of that line gets a new (and black) clef and key sig generated.
For some strange reason the layout code seems to believe that colored elements take more space than black ones?
