[pve-devel] [PATCH widget-toolkit v2] fix #6312: limit consent window to viewport size

[Dominik Csapak]

The consent window will try to size itself according to the max/min
constraints set, but those might be too large for some viewport sizes.

Since it's not possible to set those to relative viewport sizes (ExtJS
does it's own layout, so we can't use CSS), we have to save the original
size and on resize of the viewport limit ourselves to that (minus 10 px
safety margin).

Even with that the window will adhere to the set constraint sizes,
but it should be viewable with any sensible display/viewport size.

changes from v1:
* use afterComponentLayout instead of aferrender event, since the full
  layouting including sizes + constraints is done afterwards
* don't manually apply/check constraints, since that is done
  by the layouting already
* adapt commit message
