Hide Widget Title leaves container

When you select “hide widget title” it appears to use a visibility: hidden; when it would be better to use a display: none;
This means that there is a larger gap on widgets without the title showing unlike those with them showing. I have a few pages where one footer widget has a title while the other does not and the text is not lined up and looks rubbish.
I cannot add CSS to display: none; every widget as they are special per page and there are several – getting the copywriter to add CSS every time they great a new page like this is not possible, it is hard enough to get them to add the correct widget to the new page.
