Breaks a form's reset button.

To reproduce:

1. Create a simple form:

```

Submit
Reset

```
2. Load the html page and type some text in the `textarea`.
3. Click the `Reset` button. Observe that text is cleared from `textarea`.
4. From the context menu insert some lorem with "OL Insert Lorem".
5. Click the `Reset` button. Observe that text is **not** cleared from `textarea`.

We expect that the reset button will clear the text even after using "OL Insert Lorem".
