The exception shows that there is a missing style attribute in some CSS Rule obtained from the browser. I have no idea how this can happen and what it should mean. The style attribute is not optional according to the description of the protocol.

I have modified the corresponding code to log the whole content of the rule when this happens.

I am closing this issue as fixed because this exception should no longer be thrown (a different and more verbose one will be thrown).
