Bug 182505 [FieldAssist] API - ContentProposalAdapter needs hasProposalPopupFocus() method
Please implement a method ContentProposalAdapter.hasProposalPopupFocus() like org.eclipse.jface.text.contentassist.ContentAssistant.hasProposalPopupFocus(). The method should return a boolean whether the content assistant proposal popup has the focus or not.

			InfoPopupDialog(Shell parent) {
				super(parent, PopupDialog.HOVER_SHELLSTYLE, false, false,
