[Bug 56109] Broken Radiobutton navigation (Up/Down, Accelerators) in several InnoSetup installers

[WineHQ Bugzilla]

https://bugs.winehq.org/show_bug.cgi?id=56109

--- Comment #1 from KRosUser  ---
This is due to a missing BN_CLICKED notification in comctl32's button :

if ((btn_type == BS_RADIOBUTTON) || (btn_type == BS_AUTORADIOBUTTON))
            BUTTON_NOTIFY_PARENT(hWnd, BN_CLICKED);

has to be added at the very end of case WM_SETFOCUS in BUTTON_WindowProc

Note : this item is identified in the header as a "ToDo"
- WM_SETFOCUS: For (manual or automatic) radio buttons, send the parent window
BN_CLICKED
