Further information:

• It works with Firefox (62.0.3) and IE 11
• As I found out so far, the class portlet-title-editable is missing
• This class should be set by this js function (https://github.com/liferay/liferay-portal/blob/e1ac3de357b51e64ba77c121e5f65fe5b6f297f8/modules/apps/foundation/frontend-js/frontend-js-aui-web/src/main/resources/META-INF/resources/liferay/util.js#L1453)
