Content dissapears on click

[mQckingbird]

It's a weird behaviour. It must be in someplace inside this library, medium-insert-plugin or medium-editor itself.

See it running: http://codepen.io/Mr-K/pen/vGbaMy

As you can see, we have multiple instances of medium-editor working which each contains an initial value. The content is binded, and it seems ready to edit.

So far so good.
BUT when you click at it, the content is replaced by nothing. It's missing. Gone, completely.
You can see it in the codepen above.

Any clues?

Missing pen. I have the similar issue that when you input with some input method software, the first two words sometimes missing.
I can't reproduce this but i have two medium-editor instances too.
