fix: handle resize for vgrid

[vilgeforc5]

hi, I've investigated this issue #634

The problem is :

1. When mobile device is rotated, the callbacks for cell items in createGridResizer receive old values for sizes ( width and height, they're equal with previous, so we don't update anything ).
   But the callback for viewportElement receives actual value
2. You can reproduce the issue with FitToViewport story ( just chose mobile device in storybook header and rotate twice )
3. The minWidth and minHeight css properties seems to break the thing , removing them fixes the issue ( FitToViewportAdjusted story)

I'm not sure it's ok to remove those properties as it might break in some cases .. I'll look deeper later, but maybe someone has idea
