The input method doesn't work on iOS

[ITJesse]

The input method does not show the candidate box at all, so I can not enter Chinese and Japanese.

​Expected behavior:

It works prefectly in the title box, but was broken in the content box:

It just types the letter into the box without a candidate box.

Step to reproduce:

1. Use your iOS device to open the admin panel.
2. Start to write a new story.
3. Use any input method which needs a candidate box.

@ITJesse This seems to be in Ghost, right? Can you reproduce the same bug on the mobiledoc-kit demo (https://bustle.github.io/mobiledoc-kit/demo/)? If so, we know that the bug is in mobiledoc-kit itself. If not, it will be in the integration of mobiledoc-kit in Ghost.

[ITJesse]

Yes, I can reproduce it.

I did some testing, and found that the keypress event was not triggered when I press keys with input method on.

Maybe using this event to deal with these input method is not a good idea.

It's worth noting Ghost is not using mobiledoc-kit at this time, the Ghost examples provided above are using CodeMirror.
