it seems that something changed in extjs 7 which does not quite restore the correct scroll position when the identical content is set on a component. this means that sometimes, we update the text with the identical one, but the scroll position is now off, only to scroll back to the bottom this causes a flickering everytime we do the api call. instead, only update the component when the content really changed.
