Disabling Android Keyboard's 'Go' Button for WebView Text Entry

I am developing an Android application that uses a WebView pointed at a jQueryMobile-based site. Normally, disabling the 'Go' button on the soft keyboard is as simple as adding android:imeOptions="actionDone" to the control's XML tag. In the case of WebViews however, this doesn't do the trick.

How can I disable the 'Go' button from automatically doing a form submission, or alternatively to simply replace it with the 'Done' button, like android:imeOptions="actionDone" would for an EditText?
