Disabled Selectmenus: calling refresh repeatedly makes it slower and slower

[Fearodin]

Following up on case #15078:

The bug was fixed in the case above, but only for selectmenu's which are enabled.

The fix contains the creation of a new remove-eventhandler in the widget-function bindRemoveEvent().

Here, the _untrackClassesElement-Handler is added on-remove.

But the call misses the suppressDisabledCheck-Flag, which makes it useless for disabled selectmenus.

Changing the Call to the following, fixes the bug:

function bindRemoveEvent()
            {
                options.element.each(function (_, element)
                {
                    var isTracked = $.map(that.classesElementLookup, function (elements)
                    {
                        return elements;
                    })
                    .some(function (elements)
                    {
                        return elements.is(element);
                    });

                    if (!isTracked)
                    {
                        that._on(true, $(element), {
                            remove: "_untrackClassesElement"
                        });
                    }
                });
            }
