Icon separate of the bar can't move to down

[Carlos Soriano Sánchez]

I can't move down (to penultimate position) and reorder a icon if I separate the icon of the bar.
To reproduce bug:
click and separate the icon of the bar. Try to put it in the penultimate position of the bar. You can not.

Workaround:
don't separate the icon of the bar.

Possible soluttion:
It seem to be a issue in the code, in some "if" statament that allow only to n-2 and not to n-1 which is expected. (the position of n is not allowed because is the space switcher, and I don't know but you can not reorder this icon/position)
