Would be nice to get this in 0.14. I don't think it should change behavior if you're using a single React renderer. |
Should fix facebook#1939. Test Plan: With two copies of React, render a div using React1 and use that as a container to render a div with React2. Add onMouseEnter/onMouseLeave to both divs that log. Mouse around and see correct logs (as if each React was isolated), no errors.

@sebmarkbage Updated to avoid n^2 loop and removed isRenderedByReact in favor of just using getFirstReactDOM which takes about the same amount of work. |

Ok. Not too happy about this but let's work on perf / fixing the id tagging separately. |
