- Fix focus in flexbox. This required resetting the focus state at the beginning of the ComputeRequirement(), because it can now run several times. This resolves:https://github.com/ArthurSonzogni/FTXUI/issues/399 - Add Box::Union. - Add a preliminary implementation of forwarding selected_box from within the flexbox.
