Wrong selectbox rendering after reset form with scrollable.js

[TildBJ]

Wrong rendering applies to Selectboxes with scrollable.js plugin. After reset the form, the height of the select box is 0.

Hi, I'm trying to solve similar issue. Problem is with custom scroll and dropdown using jcf.

Steps to reproduce:

1. Open dropdown
2. Click outside of dropdown list to close it
3. Click "refresh all" link to refresh all jcf elements
4. Open dropdown again
5. Now it has 0px width and 0px height

Here is the fiddle: https://jsfiddle.net/kazlepka/tws1bdnh/

I was checking the code and problem is most probably in refreshing instances, even the ones that doesn't exists anymore (scrollable dropdown). It's not in DOM anymore.
