In https://github.com/phetsims/chipper/issues/1253 we are adding a lint rule that, for the most part, forbid the use of the any type specification. The Popupable.ts file is using any in its constructor so that it can work well with the other classes with which it is combined. I don't have any idea how to make this more type-specific, so I'm going to add a comment that will tell lint to ignore this for now and assign to one of the original authors.
