Uncaught Anim in browser console

2020-08-04T13:36:50Z

Hello,
I noticed there is an repeating error in browser console.

It is thrown from AUI carousel component when comment is added (<liferay:comment:discussion/>).
It is a little bit complicated to reproduce this issue (2 components located within some entry), so i have created a sample module. See attachment called entry-test.rar. It is a maven module which you can deploy to Liferay environment according to following steps:

1) Extract .rar file and copy it to to your workspace ./modules
2) Correct the name of the parent groupId/artifactId in the main pom.xml (to fit it with dependencies between modules).
3) Build and Deploy module.
4) For adding a test entry insert the following record to ns_entrytest database table:
INSERT INTO ns_entrytest VALUES ('abcd1234', 1, 0, 0, 39801, 'Test user', '2020-08-03 08:54:14.917', '2020-08-03 08:54:14.917', 'Test Title', 'Test Content');
(39801 is the userId - choose some user who is omniAdmin due to permissions - ADD_COMMENT)5) Add portlet to some page.
6) Open browser console.
7) Add some comment.
8) After comment is added and page is reloaded - see the error 'Uncaught Anim' in browser console.

Details about error
Error is repeating accordingly to the value intervalTime: 5 (Carousel component).
