Using Firefox Beta 20.0 from the Play Store on Android 4.2.2:

In adb logcat, I see this stack trace when the first character is entered in
the 'enter email address' field. The cursor then moves to the beginning of
that field.

I do not see the same issue in the most recent Release, Aurora, and Nightly
versions for Android Firefox on the same device.

(p.s., if the first character matches an address that could be previously
known, there is no exception and the options are shown).

This could possibly be an issue due to Persona code, but given that this is
only this Beta build, it seems more likely to be a generic issue.

:stomlinson or :seanmonstar might be able to help define the problem better.

we have an `onchange` listener that simply checks that the value is different from the previous one when submit was clicked, but it does nothing with a selection.

This is the HTML of that element, which looks like it tries to turn off some stuff that the Android keyboard would try to do:

    <input id="authentication_email" type="email" autocapitalize="off" autocorrect="off" spellcheck="false" value="" maxlength="254" placeholder="enter email address">

I cannot reproduce in the latest Nightly. Please reopen if it's still reproducible.
