@ddincheva , @zdrawku , @kdinev - making the bug blocking and critical as this happens on Firefox too (thought it's Edge only) . Also you don't have to scroll out of view. It is very easy to reproduce and the error thrown means we have to fix this for the release.

@ChronosSF this is the same issue. I am currently working on it.

@zdrawku , yes, you are right. I am closing this. Made the other one blocking instead.
