JavaScript Error with Emoji Script

[Presskopp]

In rare cases, I get the following error after logging in, but can't force it to reproduce so I will wait sometimes a day or more until it happens again:

Failed to execute 'observe', parameter 1 is not of type 'Node' in this line:

.observe( document.body, {

Yes I get the same error as well sometimes so would be interested in a solution.

So far it has only happened when using the Chrome browser - changing to a different computer or a different browser on same computer and it does not happen. Sometimes it goes away after a few days but I have 1 laptop where it has not gone away (but again only when using Chrome).

I think it may be some caching issue but do not know where to start looking looking or how to resolve.

I'm not sure how to reproduce this: the load() function (where this error is occurring), is only called after the DOMContentLoaded event fires, so document.body should be ready at that point.

Without a clear method to reproduce this, I'm going to close this issue for now. It can be reopened if a reliable method to reproduce this issue is discovered.
