TypeError: 'undefined' is not an object (evaluating 'a.getParent')

Users get this regularly in all browsers, though they've yet to provide me good repro steps. Current example is in Chrome 35. Error bubbles up to window.onerror.

I'm sorry but this is to little information.

1. The most important thing is providing steps to reproduce this problem. Without steps we won't be able to do anything.

Once you know how to reproduce this issue:

1. Please send us your build-config.js
2. If you have any Chrome Browser plugins, try disabling them and check this issue again.
3. If you have any third-party plugins not available in standard package, please disable them, clear browser cache (this isn't not Ctrl+F5) and recheck this issue.

Without scenario it may be hard to reproduce this, but since it's related to styles - could you attach your styles settings, which editor do you use (classic, inline, if inline, then on what element) and if possible some sample data on which it might happened.
