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.

	 *            an explicit invocation keyStroke was specified. If this
	 *            parameter is <code>null</code>, then only a specified
	 *            keyStroke will invoke content proposal. If this parameter is
	 *            <code>null</code> and the keyStroke value is
	 *            <code>null</code>, then all alphanumeric characters will
	 *            auto-activate content proposal.
