Scrollpane is jumping to bottom

Scrollpane is jumping to bottom if opening a select2 from anywhere on the page, then if trying to scroll any scrollpane object it's jumping to bottom. I fixed this temporarily by modifying this line:
from: elem.trigger('jsp-scroll-y', [-destTop, isAtTop, isAtBottom]).trigger('scroll');
to: elem.trigger('jsp-scroll-y', [-destTop, isAtTop, isAtBottom]);
