Date selection's window should stay at the same location instead of moving up or down



When selecting a date, if you change the month selected by clicking on the left/right arrow, the window moves down, and if you were clicking several times to go faster then you click outside of the window and close the date window.

Here is a screenshot for a better visualization:
You click on the “July” little arrow to move to August, but the “August” window moves down, then if you click fast and want to move to September, then your mouse stay at the same position (orange little arrow) and you click outside the August window.

It would be great if the little left/right arrows could remain at the same location.
