Row of Loaders : Row size does not reset to 0 upon loaders being destroyed

[Tadinu]

i have a Row containing some loaders like this:
Row { id: itemRow; Loader { id: loader1}; Loader { id: loader2}; Loader { id: loader3}; }

It seems that after I set a loader sourceComponent to undefined, itemRow's width and height does not reset to Zero. When I load a new component into it, it remains the previous size.
For that, I have to manually reset the size of loaders item before loading a new one into them!
Anyone having this problem?
