Function _flexslider_jqeasing_options not found [#3611006]

Problem/Motivation

Hi there,

We are in the process of upgrading from 10 to 11, and as part of that effort we are working through the issues highlighted by the Upgrade Status drupal module.

We were on an older version of Flexslider (dev-2.x tree) but we upgraded to the newer recently released 3.0 version. What we are seeing is that Upgrade Status is failing 2 checks for the FlexSlider module. While one of them is less of a blockage (its a deprecation warning) the other error is where we are stuck on.

The error has to do with a reference to a function that no longer exists in the 3.0 version.

File name -> web/modules/composer/flexslider/src/Form/FlexsliderForm.php
Line -> 101
Error -> Function _flexslider_jqeasing_options not found.

This _flexslider_jqeasing_options() function was available in the earlier 2.x series (in its .module file) but it seems to have been removed from the 3.x version however the call to it still remains in the above file.

2 questions -
1. Is this function call still supposed to be there and in use? I see here (https://www.drupal.org/project/flexslider/releases/3.x-dev) a note that jquery easing was removed.
2. Do you have any suggestions to get around this error being flagged by Upgrade Status? I suppose we can give the upgrade to 11 a try (in the interim) but we are (for obvious reasons) concerned of subsequent runtime errors when the call is eventually made.

Thanks for all of you who helped develop and support this module - much appreciated!
