MinSize ignored if Split created on invisible DOM Elements #798

Hi, there is a problem with minSize.
If Split created on hidden DOM node, this part of initialization logic at split.js @ 694, uses getBoundingClientRect. But if DOM nodes invisible at this moment (parent display:none) rect will be zero-sized, and minSize will be overwritten with 0 value. But obviously size is not === 0, it just invisible at the moment. When hidden Split became visible, it will ignore specified minSizes.
