Fixes #80470
The issue occurred when another window was about to minimize, the currently active window would become inactive temporarily and lose the keyboard focus, and then become active again after the minimizing was complete. However, the active window would not regain the keyboard focus automatically so it would not receive any
WM_CHAR
message.My solution is based on this documentation. It mentions the
DefWindowProc
function sets the keyboard focus to the window being activated and not minimized. This mechanism is not found in the current implementation ofDisplayServerWindows::WndProc
function.
