07e8ff9a8d4 Backends: Win32: Fixed a warning + moved header cruft below Changelog.
fa0120ea5ea Windows: Fixed subsequent Begin() append calls from setting last item information for title-bar. (#7506, #823)
361432a0bb2 TreeNode: fixed layout so that TreeNode("") or TreeNode("##HiddenLabel") may properly be used with SameLine(0,0). (#7505, #282)
