- Windows: BeginChild(): Fixed auto-resizing erroneously limiting size to host viewport
minus padding. There are no limit to a child width/height. (#7063) [@Devyre]
- Drag and Drop: Fixed drop target highlight on items temporarily pushing a widened clip rect
(namely Selectables and Treenodes using SpanAllColumn flag) so the highlight properly covers
