[IME] Should not be re-rendered when use input method

The case:

When the editor has video, iframe, or some complex component like MathJax, it will very clear to see the html DOM re-render.

I found onCompositionEnd event has some problems with use setTimeout to listen another composition event, and increment the forces key, and I will try to fixed it.

@sethmcleod I can’t find it in the new documentation anymore.

You have to identify your exact problem first. Does your iframe component re-render every time or does it get instantiated over and over?

In the first case, try to prevent the re-render with shouldComponentUpdate. The second case shouldn’t happen normally, but it can happen if you serialise and deserialise meanwhile. By default it will loose the keys in the state and then the component will get destroyed and instantiated again. This can be avoided if you pass a specifc option to the (de)serialise process to preserve the keys.

@ianstormtaylor This led to a very serious performance problems, the editor there is a lot of text, each time I enter Chinese, the editor will be re-rendering, very stuttering, can you provide a solution?
