Detailed Description

Regression test for BTextCtrl::LastActive(), the "which text control gets the sidebar symbols?" tracking.

It used to be a raw wxTextCtrl* inside Configuration and BTextCtrl's destructor could not unregister itself (the Configuration object dies first on some platforms, issue #2027) – so closing a wizard whose field had the focus left a dangling pointer that Worksheet::OnSidebarKey() would write into and SetFocus() on: a use-after-free. The tracking is now a wxWeakRef-backed static on BTextCtrl itself; this drives a real BTextCtrl and checks the reference nulls itself when the control is destroyed.
