the automatic code folding for JavaScript code is very buggy (Options->Code Collapse for Code). It shows lots of unwanted crosses and an equal number of ellipsis which I can't explain.
This error occurs when I close and reopen a file. Nearly each opening new crosses appear and won't disappear any more, in some files it gets out of hand like in this file, which is the worst example I've ever got:

I hope, you can reproduce this. As yet I've got this error only in the JavaScript editor and am very annoyed about these unrequested appearing crosses 'cause they make volitional code folding almost impossible.

P.S. I'm using the latest WeBuilder 9.3.0.101
