Fix Input Overwrites

[rmorshea]

Current Situation

We implemented a solution to prevent input overwrites due to the async handling of onChange. However, the same issue happens for other handlers (e.g. onKeyDown).

Proposed Actions

Generalize the solution. Instead of only applying the input solution when an onChange handler is present, always handle the input value this way.

I'm not sure if this is true in browsers besides Chrome or if this is just a behavior of React, but for some reason, the only handler which accurately gets the current value of an input is onChange.

I can't remember where I read it, but I think this is a behavior of onChange. onChange is the only event that is guaranteed to get the correct value of an input when it changes.

I'm closing for now. This issue doesn't seem to come up in practice and I'm pretty sure I've seen this happen in other app where inputs are controlled by the backend so I'm not really sure it can be fixed. Can re-open if this problem rears its head again.
