Input's onChange Event Handler Misses Key Strokes?

Discussed in #668

When I fill in the input fast it reacts slowly and miss some letters. In the example I try to write "write here the name" .

#694 does not appear to have fixed this issue.

My opinion is that if this limitation exists within React, there isn't a major reason to resolve this limitation within v1.

[rmorshea]

That's what I thought, but it turns out this is only problematic for React in the case where the onChange handler responds asynchronously. When the handling is sync, then everything works.

[Archmonger]

Do we handle this situation correctly if binding a sync IDOM event handler?

Or is it only React that behaves properly under those circumstances?

[rmorshea]

Only React behaves correctly in that circumstance.

The issue is unrelated to the server-side event handler. This has to do with the fact that the server's response to an event is async - the fact that, to trigger a re-render, we have to go to a websocket and asynchronously await a response from the server is analogous to the case where React has problems.

Would buffering received events within a queue help mitigate this? But we may already be doing this if I recall correctly.
