Builder::applyProperty resolves logical properties into physical ones. So there is no need to define BuilderCustom methods for them. Thus, most already have skip-builder:true. However, contain-intrinsic-block-size and contain-intrinsic-inline-size don't have that, and then they have some unnecessary methods in BuilderCustom.
