Cursor jump on Safari

[jinjor]

This code is problematic on Safari. (No problem on Chrome and Firefox)

input [ value = model.value, onInput = Input ] []

When any character is input, the cursor jumps to the end of the input.

4912804 says there should be no need to use defaultValue for workaround, but it still happens.

Also, this seems to cause another problem in Japanese input (or other language which uses IME).

expected

actual

IME should not commit any input until Enter key is pressed, but onSafari it does on every keypress.

Someone in elm-jp community found that 0.19 alpha does not have this problem, and this commit should be the root cause.

Apparently key !== 'value' || key !== 'checked' is always true!
I'm not confident about how to fix it, but is this enough info for you @evancz ?

Edit:
Maybe (key !== 'value' && key !== 'checked') || domNode[key] !== value is the right condition?

this relates to elm/virtual-dom/issues/134 and elm/virtual-dom/pull/135

[evancz]

Some core team folks reviewed elm/virtual-dom#135, and they tell me it should fix this. Can do a patch soon.

Nice, thank you!
