Crash in the wxComboFrameEventHandler::OnIdle method

The wxComboFrameEventHandler::OnIdle method from the common\combocmn.cpp file gets a pointer to focused window and accesses it without checking.
Situation when application has no focus is normal. Please see the attached screenshot.

wxWindow* winFocused = ::wxWindow::FindFocus();

  • Resolution set to fixed
  • Status changed from new to closed

(In [73809]) Check that focused window is non-NULL before using it in wxComboCtrl.

wxWindow::FindFocus() may return NULL, don't crash by attempting to
dereference the pointer returned by it.

Closes #15146.
