Steps to reproduce:
1-Start Liferay portal
2-Add any portlet in a page.
3-Search for the portlet service id in OSGI console.
4-Stop that osgi portlet (stop <serviceId>).
5-Refresh page where previous portlet was added
Expected behavior: You'll see a message like this: "This portlet has been undeployed. Please redeploy it or remove it from the page.", together with an option to remove the portlet when moving mouse cursor to the top right part of the portlet.
Actual behavior: You will see the message, BUT no option will show up when moving mouse cursor through the portlet. You can't remove the portlet from the page under these conditions.
