Poltergeist raises TimeoutError randomly with CKEditor

Poltergeist raises TimeoutError randomly with CKEditor.

Following steps will reproduce the problem.

1. click somewhere in page using CKEditor
2. call some Poltergeist's methods (find, evaluate_script, etc)
3. Poltergeist raises TimeoutError randomly

Please look at this repository.

As far as I have examined, Poltergeist raises TimeoutError if it with CKEditor gem or ckeditor-releases, but doesn't with ckeditor-dev (tested in this PR).
Perhaps, Poltergeist raises with minified CKEditor.

I wanted to identify the code that causes the problem, but really, it's seems difficult to me, sorry 😢

I am unable to reproduce this using the example that you provided. Poltergeist works successfully each and every time. Can you set your :debug => true option for Poltergeist and post that here for us to look at?

This is log. https://gist.github.com/mtsmfm/11115928

This is reproduced in Linux, but perhaps not in OSX.
My colleague who uses OSX couldn't reproduce this problem.

From looking at the log this seems to have been a case where the responses got out of sync with the commands sent and therefore cause all sorts of weird behavior. The out of sync behavior was fixed in poltergeist 1.8.0 so hopefully this should be fixed. If it's not we can reopen
