Possible to make primary component size less than primary-component-minsize by shrink the outer element

[starrin-zz]

If you create a vertical-split-pane, and set the primary-component-minsize(eg. 50px), and drag the separator to leftmost. Then shrink the width of the pane(like, shrink the size of the browser window), the left pane width will be smaller than 50px.
Trying to adjust the separator again will bring it back to normal.
