Just for records.
Problem is that integer type is used to store width and location.
So, when Length::calcMinValue  calculates:
return static_cast<int>(static_cast<float>(maxValue * percent() / 100.0f));

For maxValue=201px we get 100 for one float 50% and for another float 50%.
So, we get 1px gap at the right.

I'm not sure how to solve this without using floating point.
It seems that Firefox uses floating point here, because it shows 100.5px in calculated style.
