Reset BUTTON_HASFOCUS state in WM_KILLFOCUS handler before calling ReleaseCapture

[Dmitry Timoshkov]

Hello,

WM_KILLFOCUS button message handler may call ReleaseCapture, which causes
a button to receive WM_CAPTURECHANGED message. WM_CAPTURECHANGED message
handler in turn resets BUTTON_NSTATES state (as it should). But since
ReleaseCapture is been called by the WM_KILLFOCUS message handler before
resetting BUTTON_HASFOCUS state, BUTTON_NSTATES state gets reverted again.

These all leads to a misbehaviour of an app I'm working on.

    Reset BUTTON_HASFOCUS state in WM_KILLFOCUS handler before
    calling ReleaseCapture.
