Input field has inconsistent behavior whenever using focus navigation

[sleroux]

Testing on Curve 9360 w/ OS 7.0.0.319

When using multiple fields in a Smartphone WebWorks app with focus navigation enabled, you are unable to type into some of the input fields.

To reproduce this issue, I've built an app with the following index.html:

    <form>
        <input id='email' type='email' value=""><br>
        <input id='password' type='password' value=""><br>
    </form>

And in my config.xml file I've turned on focus-navigation:

<rim:navigation mode="focus"/>

When using the app,

1. Focus the first input field. Type some nonsense.
2. Move focus to next input field.
3. Typing into field will often fail. Sometimes using the backspace key then typing works.
