Following error occurs every now and then. (About every 3 minutes) Unfortunatly I don't have information, what could be the cause. As soon as I know more I'll try to build a snippet to reproduce this bug. I hope this error messages helps anyway to locate the source of the Problem.

Javascript error occurred:

In order to react fast on the issue we really need a snippet to reproduce it.

Sorry Ivan, that I did not write back sooner. 
The issue persists, but unfortunately I can't give you more information. I told our tester to run a screenrecorder while testing, so we can trace back the steps which lead to the exception. I hope, I can then produce a Snippet to reproduce this problem.
Thanks for your patience.

The issue is propably TreeRowContainer.js#_onAsyncTimer. I'll try to fix it.

Fixed in HEAD by disposing the async timer in TreeRowContainer.js
