Browse Source 
Potentially now should apply same logic to the other resizing path also described in #9060

- Windows: io.ConfigWindowsMoveFromTitleBarOnly is latched during Begin(),
effectively allowing to change the value on a per-window basis (although
there is a better internal mechanism for it).
- Windows: fixed single-axis auto-sizing (via double-clicking a border) to
take account of remaining scrollbar on the other axis. (#9060)
- Disabled: fixed a bug when a previously enabled item that got nav focus
and then turns disabled could still be activated using keyboard. (#9036)
- InputText: when buffer is not resizable, trying to paste contents that
