Am I right in thinking that React.renderComponent being async (updating the DOM) is the problem?

Add ReactUpdates.setImmediate for async callbacks
adae02b 
Callbacks passed to this setImmediate function are called at the end of the current update cycle, which is guaranteed to be asynchronous but in the same event loop (with the default batching strategy).

This is useful for new-style refs (facebook#1373, facebook#1554) and for fixing facebook#1698.

Test Plan: jest

Use setImmediate to defer value restoration
f0d9780 
Depends on facebook#1758.

Fixes facebook#1698.

Previously, controlled components would update too soon when using something like ReactLayeredComponentMixin (i.e., before the layer's updates could propagate from the parent), causing the cursor to jump even when always updating the new model value to match the DOM state. With this change, we defer the update until after all nested updates have had a chance to finish, which prevents the cursor from misbehaving.

Also cleaned up the logic around updating a bit -- the .value and .checked updates in ReactDOMInput weren't being relied on at all so I removed them and opted for a simple forceUpdate instead. I also got rid of _isChanging which hasn't been necessary since the introduction of update batching.

Test Plan: Tested the example in http://jsfiddle.net/Bobris/ZZtXn/2/ and verified that the cursor didn't jump. Changed the code to filter out numbers and verified that the field prevents typing numbers (attempting to do so still causes the cursor to jump to the end). Also verified that controlled and uncontrolled radio buttons, textareas, and select boxes work.

Is there a resolution for this within the client codebase? Looking @spicyj's fiddle (and having the exact same issue on v0.11.x), I still can't figure out the solution...

Same question here. Any workaround?

@damianmr I also thought I had a problem with it, but later discovered it was my own fault. Are maybe using value={foo} where defaultValue={foo} might do?

Nope, React shows a warning in such cases.
