Method StopDownload

src/HTTPDownload.cpp:113–119

Unlink from the request owner and cancel it. Fire-and-forget: the owner will self-destroy when wxWebRequest reports State_Cancelled on the main loop. We must NOT delete the owner here — doing so while a request is in flight leaves the wxWebRequest backend calling into a dead sink.

	// while a request is in flight leaves the wxWebRequest backend
	// calling into a dead sink.
	void StopDownload() {
		if (m_owner) {
			m_owner->DetachCompanion();
			m_owner->Stop();
			m_owner = NULL;
		}
	}

	void OnBtnCancel(wxCommandEvent& WXUNUSED(evt)) {
		AddLogLineN(_("HTTP download cancelled"));
