Race condition leading to Argument should belong to the same JavaScript world as target object

We are occasionally seeing this error come from Ferrum:

Argument should belong to the same JavaScript world as target object

From what I can tell, it may have to do with how cuprite handles finding within elements. If the page navigates in the middle of a find (in between the time when the within is resolved in Ruby to when the find is done) then the crash occurs.

page.within(:css, ".some-class") do
  page.find(:css, ".some-other-class")
end

Did you solve this?

No, we have tended to avoid within for this reason. I haven't looked into it recently as a result.
