List filtering on contenteditables broken with Android KB since 1.1

[tkalliom]

With version 1.0.1, At.js contenteditables work nicely on Android Chrome with the Android keyboard providing suggestions. Entering characters after @ filters the list correctly.

With version 1.1.0–current, entering @ opens up the suggestion list, but any further characters close it. Switching to the “no suggestions” keyboard makes filtering work again.
