     * This module containts `WeakMap`s for each effectively-"private  property" that a `Swal` has.
     * For example, to set the private property "foo" of `this` to "bar", you can `privateProps.foo.set(this, 'bar')`
     * This is the approach that Babel will probably take to implement private methods/fields
     *   https://github.com/tc39/proposal-private-methods
     *   https://github.com/babel/babel/pull/7555
     * Once we have the changes from that PR in Babel, and our core class fits reasonable in *one module*
     *   then we can use that language feature.
