After deploying the Chat portlet (built from liferay-plugins master) to Liferay 7.0 CE built from liferay-portal master, the items in the Product and Add menus overlap with each other (attached screenshots chat-01 and chat-02). The Chat portlet's contents also render as part of the page, instead of in a bar on the bottom of the screen (attached screenshot chat-03). Oddly enough, these bugs don't occur at the same time... only one appears at a time. The below console error also appears.
